Force |
A push or pull |
|
|
|
Contact Forces |
A force exerted on an object through direct contact |
|
|
|
Non contact Forces |
A force exerted on an object by another object that are not touching |
Example: Gravity |
|
|
Unbalanced Forces |
When the net forces are not zero |
|
|
|
Balanced Forces |
When the net forces are zero |
|
|
|
When forces are balanced... |
No motion occurs |
|
|
|
When forces are unbalanced... |
Motion occurs |
|
|
|
Sliding Friction |
The force of friction that opposes the motion of a sliding object |
|
|
|
Elastic Force |
The force exerted by a material when it is streched or compressed |
|
|
|
Tension Force |
A pulling force that can make an object stretch |
Example: squeezing a rubber ball |
|
|
Compression Force |
Be squeezing force applied to an object that can make an object shrink |
Example: squeezing a rubber ball |
|
|
Normal Force |
A force exerted by an object that is perpendicular to the surface of the object |
Example: a person sitting on a chair. The chair exerts in normal force on the person. |
|
|
Unbalanced forces on an object at rest causes... |
The object to accelerate |
|
|
|
Unbalanced forces on an object in motion causes... |
The object to either speed up or slow down |
|
|
|
Centripetal Force |
The force that is perpendicular to the velocity and toward the center of the circle |
|
|
|
Newton's second law of motion |
Acceleration of an object equals the net force divided by the object's mass |
A= F/M |
|
|
Newton's third law of motion |
When an object exerts a force on the second object, the second object exerts on an equal force in the opposite direction of the first object. |
