MFE- Acceleration

Acceleration refers to…

the rate at which velocity changes.

What are the three changes in velocity that are called acceleration?

increasing speed, decreasing speed, or changing direction.

True/False: A train that never changes speed but goes through bends accelerates.

True (It changed direction)

What information is needed to calculate acceleration?

final speed, initial speed, and time

What is the formula for acceleration?

Final speed - initial speed/time

A unit of acceleration is

Graphs that be used to show acceleration are…

speed versus time, distance versus time

True/False: A ball that is thrown through the air accelerates.

True (it increases speed and changes direction)

Why is planet Earth always accelerating?

It is always changing direction.

Usually, the term for decreasing speed is…

deceleration.
