Acceleration

Question 1

What does it tell?

Answer 1

Acceleration tells how much an objects speed changes in one second.

Question 2

Objects speeds up

Answer 2

When an object speeds up, its acceleration is in the direction of the motion.

Question 3

Objects slow down

Answer 3

When an object slows down, its acceleration is opposite the direction of motion.

Question 4

Free fall

Answer 4

Objects in free fall gain or lose 10m/s of speed every second.

Question 5

Steady speed equation

Answer 5

When an object is moving at a steady speed v, it travels a distance given by d=vt.

Question 6

At rest or speeds up equation

Answer 6

When an object starts at rest and speeds up, or when an object slows to a stop, the distance traveled is given by either d=1/2at^2 or d=v^2/2a.
