Momentum

Front

What is momentum?

Back

Momentum is a measure of the motion of an object and is defined as the product of its mass and velocity. It is a vector quantity.

Front

What is the formula for calculating momentum?

Back

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

Front

What is the unit of momentum?

Back

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

Front

What is the unit for mass?

Back

The unit for mass is kg (kilogram).

Front

If a 50 kg ball rolls at 5 m/s, what is its momentum?

Back

The momentum is 250 kg*m/s.

Front

How does mass affect momentum?

Back

Momentum increases with an increase in mass, assuming velocity remains constant.

Front

How does velocity affect momentum?

Back

Momentum increases with an increase in velocity, assuming mass remains constant.

Front

If an object has a momentum of 40 kg*m/s and a mass of 60 kg, what is its velocity?

Back

The velocity is 0.67 m/s.

Front

What is the relationship between momentum and kinetic energy?

Back

Momentum and kinetic energy are related; as momentum increases, kinetic energy also increases, but they are calculated differently.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before and after an event (like a collision) remains constant.
