A quantity that has both magnitude and direction.

• Scalar
• Mass
• Speed
• Vector

Quantity with magnitude only

• Vector
• Scalar
• Force
• Friction

A push or pull, measured in Newton's.

• Force
• Mass
• Coefficient of Friction
• Drag

What is Newtons 2nd law of motion?

• Pancakes 
• Force= Mass multiplied by acceleration
• For every action there is a equal and opposite  re-action.
• Law of gravity 

Baseball pushes glove leftwards. What is the re-action 

• The glove pushes the baseball rightward.
• The glove pushes the baseball leftward 
• It stays still
• The glove pushes the baseball upward 

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object?

• 150 Newtons
• 15 Newtons
• 150 kilograms
• 100 kilograms

A 0.250 kg cart moving at 0.400 m/s has how much momentum?

• 0.1 kg-m/s
• 1 kg-m/s
• 10 kg-m/s
• 100 kg-m/s

When the speed of an object is doubled, its momentum

• remains unchanged in accord with the conservation of momentum.
• doubles
• quadruples
• decreases

The formula for momentum is

• mass divided by velocity
• mass multiplied by velocity
• velocity divided by mass
• Force times acceleration

Which graph represents an object at rest?

• 1
• 2
• 3
• 4
