TRUE or FALSE ? Acceleration occurs when going in a circle.

Acceleration occurs when slowing down on a

bicycle.

Acceleration occurs when skating at constant

speed in straight line.

Acceleration occurs when speeding up in car.

Each time you take a stepyou are changing thevelocity of your body.

You are probably mostfamiliar with the velocitychanges of a moving busor car.

The rate at which velocity(speed or direction)changes occur is calledacceleration.

The constant accelerationof an object moving onlyunder the force of gravity is"g".

The acceleration caused by

gravity is 10 m/s2 If there was no air, all

objects would fall at thesame speed

Doesnt depend on mass After 1 second falling at 10

m/s

After 2 seconds 20 m/s

3 seconds 30 m/s
