What is the difference between static and kinetic friction. Define both, write their SI unit and dimension. Write down the mathematical statement (formula) that allows us to calculate the force of friction. Explain each term with its unit. Let’s say you’re dragging a 50 kg rubber box on wet concrete. How do you calculate the force of friction on this box?
Which statement about friction and normal force is true? a. Kinetic friction is always in the direction of the normal force. b. Static and kinetic friction do not depend on the normal force. c. Static and kinetic friction forces are linearly related to the normal force. d. Static friction is always in the direction of the normal force.
1. Describe the difference between static friction and kinetic friction. 2. You have a 1.20 kg cart resting on various surfaces. For each of the following scenarios, find the normal force acting on the cart (in standard units): a. The cart on a horizontal floor b. The cart carrying a load of 750 g on a horizontal floor c. The cart on an incline raised 15° above the horizontal d. The cart on a horizontal floor with a string attached...

Antilock breaks are important because: The kinetic friction force is greater than the maximal static friction force, so preventing the tire from skidding allows for more stopping force. When the wheels are turning and the car is slowing down, the static friction force is in the forward direction unless the car skids skidding does not provide a static friction force motion against the direction d None of the above is correct.
A 24-N block rests on a horizontal surface. The coefficients of static and kinetic friction between the surface and the block are ?s=0.76 and ?k=0.34. A horizontal string is attached to the block and a constant tension T is maintained in the string. blem 5-23a: A 24 N block rests on a horizontal surface. The coefficients of static and kinetic friction between the surface and the block are us=0.76 and μk=0.34. A horizontal string is attached to the block and...
