Force
- That which causes an object of mass to change in its motion (it changes its velocity), if it is not balanced.
- A pull is basically a push in the opposite direction
- Can be categorised;
| Contact | Non-Contact | |
|---|---|---|
| Push | Shove, Kick, Punch | Magnetism, Same Poles |
| Pull | Grab, Hug, Tug of War | Magnetism, Opposite Poles, Gravity |
3 Laws
- An object of mass will continue in its state of motion unless acted upon by an unbalenced force. Motion = velocity.
- Basically $f=ma$. The acceleration of an object of mass is proportional to the unbalanced force acting on it and inversely proportional to its mass
- Every action force has an equal and opposite reaction force.
