SUMMARY OF FORCES
A force is an influence that can change the motion of an object. A force has both magnitude and direction, making it a vector quantity.
There are two types of force, they are; contact force and non-contact force/force field.
A contact force is any force that requires contact to occur. Force field is a force whose source does not require contact with the object to which it is applied. It occurs between two bodies or objects that are separated by space.
A centrifugal force acts in a direction away from the centre of a circle. The centripetal force acts in a direction towards the centre of the circle.
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
