Question

True or False?

a) If two objects have the same acceleration, they are under the influence of equal forces.

b)An object initially moving at a constant velocity will slow down unless net force is applied.

c)The net force which acts on an object which maintains a constant velocity is zero.

d)During the collision of a car with a large truck, the truck exerts an equal size force on the car as the car exerts on the truck.

e)During the collision of a car with a large truck, the car exerts a lesser force on the truck than the truck exerts on the car.

A) False
They might have different masses

B) False
Unless there is an external force, velocity will not change (friction is also an external force)

C) True

F = 0 means a=0, thus velocity constant

D) True
Forces are equal and opposite

E) False
