A force is a push or a pull. It is also a vector; It has size and direction. There are three common forces.
- Contact force is a force applied by touching.
- Gravity is the force of attraction between two masses.
- Friction is the force that resists motion between two surfaces pressed together.
These humans in the pictures give 2N It is balance force.
Balance force is the net force that acting on a object is 0
Unbalance Force
These humans in the pictures give 2N In the left picture, it is unbalance force.
Unbalance force is the net force that acting on a object isn’t zero
Touch Force
We called touch force
because we give force with touch the object
The picture shows the touch force from the cue ball
(Note. The cue ball didn’t show here)
Untouch (Field) Force
We called untouch force
because we give a force without touch the object
For example :
- Weight
- Magnetic
