When a force F acts on a body for a time interval t, the product F x t is known as
AMomentum
BImpulse
CTorque
DAcceleration
Answer & Solution
Correct answer: B. Impulse
1. A large force acting for a short time is an impulsive force.
2. The product of force and the time for which it acts is impulse, J = F x t.
3. Impulse also equals the change in momentum, with unit N s.
