Momentum and Collisions

Front

What is momentum?

Back

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

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

How do you calculate the momentum of an object?

Back

Momentum (p) is calculated using the formula p = mv, where m is the mass of the object and v is its velocity.

Front

What happens to the momentum of a falling object as it descends?

Back

The momentum of a falling object increases as it descends due to the increase in velocity caused by gravity.

Front

At what point does a falling object have the greatest momentum?

Back

A falling object has the greatest momentum just before it impacts the ground.

Front

What factors affect the momentum of an object?

Back

The momentum of an object is affected by its mass and velocity. Increasing either mass or velocity increases momentum.

Front

If two objects have the same mass, how does their momentum compare if they have different velocities?

Back

The object with the higher velocity will have greater momentum.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg m/s).

Front

Can momentum be negative?

Back

Yes, momentum can be negative if the object is moving in the opposite direction of the defined positive direction.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.
