m/s (meters/second)
Which is faster- 5 m/s or 10 m/s?
10 m/s
What is the unit for force?
Newtons (N)
What is a balanced force?
When 2 forces act on something but there is no movement.
A force that slows down objects when they rub against each other
Friction
The force that pulls objects towards the center of the Earth
Gravity
