Force and Energy

What is a force?

• the speed and direction of an object

• a push or pull

• a change in an objects position

• a change in velocity

What is velocity?

• a change in velocity over time

• the speed and direction of an object

• a change in position over time

• the ability to do work

What is friction?

• a push or pull

• the speed and direction of an object

• a force between surfaces that slows objects or stops them from moving

• a change in an objects positoin

What is acceleration?

• the tendency of an object at rest to stay at rest and an object in motion to stay in motion

• a change in VELOCITY over time

• how fast an object's position changes over time at any given moment

• the ability to do work

What is motion?

• the ability to do work

• a football play

• a change in an objects position

• when two or more objects hit one another

What is speed?

What is inertia

• speed

• the tendency for an object at rest to stay at rest and an object in motion to stay in motion

• energy cannot be created or destroyed it can only be changed

• a push or pull

What is a collision?

• a push or pull

• when two or more objects crash into one another with force

• energy cannot be created or destroyed

• a type of ice cream

What is the Law of Conservation of Energy?

• energy cannot be created or destroyed only transferred or transformed (changed)

• the tendency for an object at rest to stay at rest and an object in motion to stay in motion

• the ability to do work

• a push or pull
