Physics for IGCSE & O level - Forces And Motion (Section 10 - No. 39)
If two objects have the same momentum, what must be true?
They have the same mass.
They have the same velocity.
They have the same mass and the same velocity.
Mass and velocity can vary as long as their product remains the same.
توضیح
Momentum is the product of mass and velocity, therefore there are numerous combinations which provide the same momentum value.
