NOTE
MOTION IN NATURE
Motion is the change of position of a body with time. The study of motion without involving the force causing the motion is called kinematics. The study of motion of objects and the forces acting on them is called dynamics.
Types of Motion
Relative Motion
If two bodies, A and B are moving on a straight line, the velocity of A relative to B is found by adding the Velocity of B revered to the velocity of A. For instance, if a car traveling on a straight road at 100km/hr passes a bus going in the same direction at 60km/hr., the velocity of the car relative to the bus is (60+100) = 40km/hr. If the car and the bus are traveling in opposite direction with the same velocities of 100km/r and 60km/hr respectively, the velocity of the car relative to the bus is ( (60) + 100) = (60 +100) = 160 km/hr.
NB: When the velocities are not in the same straight line, the parallelograms law should be used to add this since velocities are vectors, and their magnitudes and direction must be taken into consideration.
CAUSES OF MOTION
All objects will continue in their state of rest unless acted upon by force. Only the application of a force can cause visible motion. Hence, force causes motion. There are two types of force (a) Contact force (b) Field force
CIRCULAR MOTION
In physics, circular motion is movement along a circular path or orbit. It can be uniform (i.e. with constant angular rate of rotation) or nonuniform (i.e. with a changing rate of rotation)
Formulae for uniform circular motion
Consider a body of mass (kg), moving in a circle of radius r (m), with an angular velocity of ω (rads^{1})
(To convert radian from degree 360^{0}=2∏)
CENTRIFUGAL FORCE
Centrifugal force is a force that acts in opposite direction to the centripetal force.
Centrifugal force is an outward force associated with rotation.
