An acceleration.
1 of 12
What is a deceleration?
A negative acceleration.
2 of 12
What happens if there is no acceleration?
The reultant force must be zero.
3 of 12
What is acceleration?
A change in velocity.
4 of 12
How can an object change acceleration if it is going at a constant spped?
It can change direction.
5 of 12
What is needed to change direction?
A resultant force.
6 of 12
What is the resultant force equation?
F=m x a
