Question

A particle is moving with a constant speed along a straight-line path. A force is not required to

• A. Change its direction
• B. Decrease its speed
• C. Keep it moving with uniform velocity
• D. Increase its momentum

Hint:

In Newton's first law, an object moving at constant velocity requires no force to continue its motion in the absence of other forces.

Answer 1

The Correct Option is C

Step 1: Apply Newton's First Law of Motion.
Newton’s first law states that an object will remain at rest or in uniform motion unless acted upon by an external force.

Step 2: Understand uniform velocity.
A particle moving with a constant speed along a straight-line path does not need a force to maintain its motion if there are no external forces acting on it.
This is because no force is required to keep an object in uniform motion.
