MCQ
A uniformly accelerated body has $..........$
- AConstant speed
- BConstant velocity
- ✓Constant force
- DConstant momentum
✓
Answer
Correct option: C.
Constant force
Since the body is accelerated, the speed and velocity will vary.
Momentum depends on velocity;
hence the momentum will also vary.
The force remains constant as $F = ma.$
Momentum depends on velocity;
hence the momentum will also vary.
The force remains constant as $F = ma.$
