Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as the product of force and time (Impulse = Force x Time).

What is the formula for calculating momentum?

Back

The formula for momentum (p) is p = mv, where m is mass and v is velocity.

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming velocity remains constant.

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

If a 10 kg object is moving at 3 m/s, what is its momentum?

Back

30 kg*m/s (p = mv = 10 kg * 3 m/s).
