Physics Final Review

Find the speed of a 5 kg object that travels 10 m in 4 seconds

• 50

• 2

• 2.5

• 40

Velocity is

• the same as speed

• the opposite of speed

• the same as acceleration

• speed in a specific direction

Positive acceleration is

• speeding up

• slowing down

• moving backwards

• speed in a forward direction

Negative acceleration is

• speeding up

• slowing down

• moving backwards

• speed in a forward direction

What is the acceleration of a 15 kg object that takes 2 seconds to go from 10 m/s to 20 m/s?

• 5

• 10

• 150

• 15

Force is

• a push or a pull

• an acceleration

• something that resists motion

• a property of matter

Gravity is

• the attraction that pulls us towards Earth

• very strong

• a push or a pull

• a force that resists motion

How do we calculate weight?

• F=ma

• V=IR

• GPE=mgh

• W=Fd

Objects in space still have mass. This means they have

• inertia

• friction

• gravity

• acceleration

According to Newton, once you get something moving, it will

• continue moving

• slow down by itself

• speed up by itself

• have potential energy
