Momentum

Front

What is momentum?

Back

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

Front

What is the formula for calculating momentum?

Back

p = m x v, where p is momentum, m is mass, and v is velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

If a 1000-kg car is moving at 20 m/s, what is its momentum?

Back

20000 kg*m/s south.

Front

Which has more momentum: a rolling bowling ball or a rolling ping-pong ball at the same speed?

Back

A rolling bowling ball has more momentum due to its greater mass.

Front

How does mass affect momentum?

Back

Momentum increases with an increase in mass if velocity remains constant.

Front

How does velocity affect momentum?

Back

Momentum increases with an increase in velocity if mass remains constant.

Front

Calculate the momentum of a 50 kg ball rolling at 5 m/s.

Back

250 kg*m/s.

Front

What is the relationship between momentum and kinetic energy?

Back

Momentum is related to kinetic energy, but they are different concepts; kinetic energy is given by KE = 1/2 m v^2.

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.
