## What type of acceleration does an object moving with constant speed in a circular path experience? A) free fall. B) terminal acceleration. C) constant acceleration. D) linear acceleration. E) centripetal acceleration.When an object experiences uniform circular motion, the direction of the net force is A) in the same direction as the motion of the object. B) in the opposite direction of the motion of the object. C) is directed toward the center of the circular path. D) is directed away from the center of the circular path. E) is dependent on the speed of the object.Consider a particle moving with constant speed such that its acceleration of constant magnitude is always perpendicular to its velocity. A) It is moving in a straight line. B) It is moving in a circle. C) It is moving in a parabola. D) It is moving in a hyperbola. E) None of the above is definitely true all of the time.For an object that travels at a fixed speed along a circular path, the acceleration of the object is A) larger in magnitude the smaller the radius of the circle. B) in the same direction as the velocity of the object. C) smaller in magnitude the smaller the radius of the circle. D) in the opposite direction of the velocity of the object. E) zero.

## When a car goes around a curve, it has a tendency to skid outwards. Is the frictional force between the tires and the ground that keeps the car from skidding kinetic or static? A) kinetic B) static.A flatbed truck is carrying a crate along a level road. The coefficient of static friction between the load and the bed is 0.40. The truck accelerates forward and the crate stays in its place on the truck bed. In what direction is the force that the bed exerts on the crate? A) forward B) backward C) toward the center of the road D) There is no frictional force because the crate does not move with respect to the bed. E) There is not enough information to answer this question.As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is A) static friction. B) kinetic friction. C) a combination of static and kinetic friction. D) neither static nor kinetic friction, but some other type of friction. E) It is impossible to tell what type of friction acts in this situation.
