Newton's 2nd Law of Motion (Acceleration)

What are three ways you can accelerate?  (Click 3 answers)

• Slow down

• Speed up

• Stop

• Change direction

Why is acceleration different from speed?

• Acceleration makes an object harder to stop.

• Acceleration is distance/time without direction.

• Acceleration is a change in velocity, which includes direction.

• Acceleration is distance/time with direction.

If an object slow down, it is considered- 

• acceleration

• velocity

• speed

• momentum 

What is deceleration?

• A type of acceleration that slows down.

• A type of speed that changes distance.

• A type of momentum that has a lot of mass.

• A type of velocity that changes direction.

Which of Newton's Laws talks about inertia?

• 1st

• 3rd

• 2nd

What does friction do to an object?

• Keeps it the same

• Slows it down

• Speeds it up

Force changes the-

• direction.

• speed.

• velocity.

True or False:

A change in direction is acceleration.

• False

• True

What causes acceleration?

• Force

• Speed

• Velocity 

• Friction
