Physics Flashcards
The rate at which velocity changes
Acceleration of
How do you change acceleration
Speed up, slow down, or change direction
+ acceleration +velocity
Moving right, speeding up
-acceleration + velocity
Moving right, slowing down
+ acceleration- velocity
Moving left, slowing down
- acceleration - velocity
Moving left, speeding up
What is force
A push or a pull exerted on an object
Causes of force
A change in motion, adding energy to an object
unit of force
N- newton
1N=1kg x 1m/s2
Contact forces
The objects have to physically touch
- applied forces
- spring force
- drag force
- fictional force
- normal force
Field forces
The objects don’t actually have to touch to attract
- nuclear forces
- magnetic force
- electric force
- gravitational force
Normal force
The force that supports the weight of an object
