Momentum Concepts and Calculations

Front

What happens to the momentum of an object when its speed is doubled?

Back

The momentum doubles.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

The bike has more momentum.

Front

If a wagon's mass doubles while no external forces act on it, how does its velocity change?

Back

The new velocity is 1/2 as much.

Front

What two factors does the momentum of an object depend on?

Back

Mass and velocity.

Front

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

Back

0.67 m/s.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

How does increasing mass affect momentum if velocity remains constant?

Back

Increasing mass increases momentum.

Front

How does increasing velocity affect momentum if mass remains constant?

Back

Increasing velocity increases momentum.

Front

What is the unit of momentum in the International System of Units (SI)?

Back

Kilogram meter per second (kg·m/s).
