Question

Indicate whether the following statements concerning Newton's Laws are true or false.

(Select T-True, F-False. If the first is T and the rest F, enter

TFFFF).

A) If a single force acts on an object, the object accelerates.

B) If an object isn't moving, no external forces act on it.

C) If an object is accelerating, a force is acting on it.

D) An object's velocity will only be in the direction of the net force exerted on it.

E) It is impossible to have motion in the absence of a force.

Step 1

A)

Since single force is acting on the object, it will accelerate. Acceleration will be equal to the ratio of force and mass of the object. The statement is true.

Step 2

B)

If the net force on the object is zero, then the object doesn’t move. Consider the case where two equal and opposite forces act on an object at rest. The net force is zero and hence the object will not move. The statement is false.

Step 3

C)

Only when a force acts on an object, it will...
