Question

An object will continue moving uniformly until

• A. The resultant force on it is zero.
• B. The resultant force on it increases continuously.
• C. The resultant force is at a right angle to its rotation.
• D. The resultant force acting on it beings to decrease.

Answer 1

The correct option is A

The resultant force on it is zero.

1. Newton's first law of motion is also known as the law of inertia.
2. The law states that a body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it.
3. Hence, an object will continue moving uniformly until the resultant force on it is zero.

Hence, option A is correct.
