Momentum

What is momentum?

• The addition of an object's mass and velocity
• The subtraction of an object's mass and velocity
• The product of an object's mass and velocity
• The division of an object's mass and velocity

What symbol represents momentum?

• m
• p
• v
• N

What symbol represents velocity?

• p
• m
• N
• v

What symbol represents mass?

• v
• p
• m
• N

How are units of momentum expressed? 

• m/s
• kg
• kg-m/s
• m/s-s

When two objects collide, what happens to all of the momentum?

• It Increases
• It remains the same
• It vanishes
• It decreases

When objects collide, the total amount of momentum stays the same. This states....

• The law of conservation of momentum.
• law of conservation of energy
• Newton's 1st Law
• Newton's 2nd Law

Calculate the momentum of an object with a mass of 100 kg that moves with a velocity of 20 m/s west.

• 200 m/s
• 2000 kg-m/s
• 2000 m/s
• 200 kg-m/s

When mass changes, the velocity must change too.

• True
• False

Conservation of Momentum is explained by

• Newton's 1st Law
• Newton's 3rd Law
• Newton's 2nd Law
