Question
A body is moving at a constant speed in a straight line path. A force is not required to.
- increase its speed
- change the direction
- decrease the momentum
- keep it moving with uniform velocity
Answer
keep it moving with uniform velocity
Explanation
A force is not required to keep a body moving at a constant speed in a straight line path. According to Newton’s first law of motion, a body will continue to move with uniform velocity in a straight line path unless acted upon by an external force. In the absence of external forces, the momentum of the body will remain constant, and therefore, the body will continue to move with a constant speed in a straight line path. Therefore, the correct answer is “keep it moving with uniform velocity”.
