Question
Indicate whether the following statements are always true or can be false.
(Select T-True, F-False. If the first is F and the rest T, enter
FTTTTT).
A) A car initially moving at a constant velocity will slow down unless a small net force is applied.
B) The net force which acts on an object which remains at rest is zero.
C) If two objects are under the influence of equal forces, they have the same acceleration.
D) If a net force acts on an object, the object's speed will change.
E) If a net force acts on an object, the object's velocity will change.
F) During the collision of a large truck with a car, the car exerts an equal size force on the truck as the truck exerts on the car.
Explanation / Answer
A) False, (a net force means there would be some acceleration)
B) True
C) False(it also depends on their masses)
D) False (In uniform circular motion a force is present which just changes the velocity not the speed)
E) True
F) True
