Understanding Momentum

What is the formula for calculating momentum?

• momentum = mass x velocity

• momentum = mass + velocity

• momentum = mass - velocity

• momentum = mass / velocity

How is momentum defined in physics?

• Momentum is defined as the speed of an object.

• Momentum is defined as the product of an object's mass and velocity.

• Momentum is defined as the square of an object's mass.

• Momentum is defined as the product of an object's weight and velocity.

What are the units of momentum?

• m/s

• kg

• N*m

• kg*m/s

Explain the principle of conservation of momentum.

• Momentum can be created or destroyed during an event

• Conservation of momentum only applies to objects at rest

• The total momentum before an event must be equal to the total momentum after the event.

• The total momentum before an event is always less than the total momentum after the event

How does mass and velocity affect an object's momentum?

• Both mass and velocity directly affect an object's momentum.

• Velocity is the only factor affecting momentum

• Mass has no impact on momentum

• Momentum is not influenced by mass or velocity
