Mechanics Review

Force is directly related to acceleration.

• True

• False

A positive acceleration ALWAYS causes an object to speed up.

• True

• False

A negative acceleration ALWAYS causes an object to slow down.

• True

• False

A larger change in time will result in a smaller force.

• True

• False

A larger change in time will result in a larger force.

• True

• False

The slope of a position v. time graph is...

• velocity

• acceleration

• seconds

• meters

The slope of a velocity v. time graph is...

• velocity

• acceleration

• meters per second

• meters

You walk 10 meters to math class in 20 seconds. Your velocity is...

• 2 m/s

• 0.5 m/s

• 200 m/s

• 5 m/s

Change in velocity over a given period of time is...

• position

• motion

• speed

• acceleration

On a distance vs. time graph, the steeper the slope...

• the slower the speed

• the faster the speed

• less acceleration

• greater acceleration
