An experiment on the effects of weight on speed and friction

an experiment on the effects of weight on speed and friction Objects indeed undergo acceleration and later continue with near-constant or terminal velocity with air resistance in the earth's atmosphere slope also affects velocity, and friction from the material affects maximum terminal velocity however, given the same mass and material, larger objects will exhibit.

Experiments were carried out under normal load 10-20 n, speed 500-2500 rpm index term— friction coefficient, normal load, sliding speed, wear rate i introduction study of mechanics of friction and the relationship between friction and of putting dead weight on it so that required normal force will act on the. Thinking about the coefficients of static and kinetic friction coefficients of friction can only be determined by experiment so i have got this block of wood here that has a mass of 5 kilograms and it is sitting on some dirt and we are near the surface of the earth and the coefficient of static friction between this type of wood. Friction: friction, force that resists the sliding or rolling of one solid object over another two simple experimental facts characterize the friction of sliding solids first which implies that a force equal to half the weight of the bricks is required just to overcome friction in keeping the bricks moving along at a constant speed. Weight affects friction in that friction is directly proportional to the weight of the load one is moving if one doubles the load being moved, friction increases by a factor of twofriction is the force that opposes motion of one object over another friction is sometimes beneficial as when preventing slipping of the feet when. Investigating sliding friction: the effect of weight on sliding friction between a block and surface i will use this information to record the force of friction because when i pull the block my pulling force will be measured on the newton meter, so therefore if the block is moving at a steady speed the force of friction will be the. Repeat step 12 with block b pull block a across the table at a constant speed if the speed is constant, then the force reading on the scale should be equal to the frictional force calculate equation 11 for block a do this five times and record the average value repeat step 14 with block b 2 effect of weight on the force of. In this investigation we are going to find out what effect weight has on sliding friction friction is the force that is between two objects that are in contact with each other the force is always present even though people only think it is there when the object is moving leonardo da vinci was one of the first people to experiment. Speed increases measurements of the cof at high sliding speeds were obtained by bouncing a tennis ball obliquely off a surface the experiments were conducted in part to extend the range of sliding speeds, but also to determine whether the cof for a short impact is the same as that found when sliding is maintained.

2b students know when an object is subject to two or more forces at once, the result is the cumulative effect of all the forces 2d students know how to identify separately the two or more forces that are acting on a single static object, including gravity, elastic forces due to tension or compression in matter, and friction 2g. Out my work in this group i've not only learned about cooperative effects in the experiments this raises questions about criticality of the system the force released when a single carpet fiber snaps is often too small for the resolution in the coulomb assumed friction was independent of the velocity, but stick-slip mo. How were the effects of friction and gravity minimised in the experiment exam solutions a force is anything which can cause an object to accelerate a force of 1 n gives a mass of 1 kg an acceleration of 1 m s-2 newton's first law of motion states that an object stays at rest or moves with constant velocity unless an external.

This frictional force depends on two things firstly, the nature of the object and also the friction of the surface itself secondly, the force between the object and the surface, so it will be harder to push the object over the surface if the downward force of the object, the weight, increases in my experiment, i will be investigating. Notice we've chosen her weight so that, conveniently, she plus the ball weigh just ten times what the ball weighs by itself what is found on doing this experiment carefully is that after the catch, she plus the ball roll backwards at just one-tenth the speed the ball was moving just before she caught it, so if the ball was thrown at. As you've most likely taught your students, gravity is the force that exists between any two objects that have mass weight is a measure of the force of gravity pulling on. After watching this video, you will be able to explain why friction exists when two surfaces move alongside each other we'll also conduct.

Record the force needed to start the mass moving (this will be less than the force to pull it along once it is moving) increase the height of the ramp to 10 cm to make the gradient steeper measure the force repeat by moving the ramp up in 10 cm intervals until 50 cm is reached experiment to investigate frictional forces. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat) this property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire kinetic energy. Abstract the funny thing about friction is that you couldn't get anywhere without it , yet it still acts to slow you down as you're getting there here is an easy project to measure the effects of friction objective the goal of this project is to investigate how far equally-weighted objects with different surface textures will slide when.

The amount of potential energy depends on the object's mass, the strength of gravity and how high it is off the ground when you drop the object, this potential energy is converted into kinetic energy, or the energy of motion kinetic energy depends on an object's mass and its speed ignoring frictional losses. This will let you make a more reliable measurement of the force of friction place the plank on rollers pull it along at a constant speed using the string and crank drag the block along with the forecmeter c ask students to predict the effect of dragging the surfaces across each other at different speeds show them what.

Thus be a good starting point for investigating friction figure 1: note taking during the experiments and an example of a tablet protocol from the investigations in with mass m if the body is at rest (or moving with constant speed), the upward friction force must be f= mg sin θ to counteract the tangential component of the. Test which surfaces create more friction, see how strong friction is, learn how to reduce friction, and even discover the side effects of friction there are sliding friction experiments, a phone book friction experiment, a way to make rice stick together, an experiment to create frictional heat, and lots more friction.

Kids learn about the science behind friction including how it works as a force to slow things down, how it helps us stand, preventing friction, types, and fun facts. Falling objects increase their speed as they fall, because their weight (the force of gravity) pulls them to earth they also experience an upward force called air resistance (drag), which slows them down objects fall faster until they reach their terminal speed, which is reached when the upward (air resistance) and downward. If you're looking for an illuminating yet straightforward science project, investigating the effect of mass on the distance a ball travels is a fantastic choice friction depends on the mass of the object too, but the link between mass and acceleration shown by newton's second law also means that it takes more.
