Question
An object following a straight-line path at a constant speed has _____.
- a = 0
- F = 0 N
- Both A and B
- m = 0 Kg
Hint:
a = 0 Is the correct answer.
The correct answer is: a = 0
If a body is following a straight line path with a constant speed then no net force is acting on it, therefore its acceleration is zero.
