What is gravity?

what is friction?

force

• is a change in a object´s position

• any push or pull

• is how fast an object´s position changes over time

• is the speed an direction an object

Motion is . . .

velocity is . . .

friction

• any push or pull

• is the ability to do work

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

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

speed is . . .

balanced forces

• is a change in an object´s position

• forces that act on an object without changing its motion

• a change in velocity over time

• forces that act on an object changing its motion

unbalanced forces is . . .
