Question

What is the difference between force and momentum ?

Answer 1

• Force is an external cause, while momentum is an internal property of matter.

• A force is required to change the momentum of any object.

• The net force on an object can be defined as the change of momentum per unit time.

• Both force and momentum are vectors.

• Force is the time derivative of the momentum.

Answer 2

FORCE

1. Force is an external cause on the object.
2. Force may be applied to accelerate or stop an object.
3. Unit of force is N
4. F = ma
5. Force is ''vector quantity''
6. Force is required to change the momentum of an object.

MOMENTUM

1. Momentum is the property of the object on the application of force.
2. An object with momentum is always moving.
3. Unit for momentum is kg m/s
4. P = mv
5. Momentum is ''vector quantity''
6. Momentum is the result of applied force.
