Speed

Speed is a scalar quantity.

It is the rate of change of position(distance) of an object with time in any direction

Basically speed = ds/dt

Or

Speed = Distance Travelled  / Time Taken

Types of Speed:

1) Uniform Speed

- an object is moving in uniform speed if it covers equal distances in equal periods of time.

2) Variable Speed

- an object is moving in variable speed if it covers unequal distances in equal periods of time.

3) Average Speed

Average Speed = Total distance traveled / Total time taken

Velocity

Velocity is a vector quantity. It is the rate of change of position of an object with  period of time but in a fixed direction. - Has the same definition as speed but it has a given direction as well. Velocity = Displacement/ Time

Acceleration

Acceleration = the rate of change of the velocity of an object with time - how fast the velocity of an object changes with time Acceleration = Change in Velocity / Time Taken - a vector quantity measured in m/s^2 or ms^(-2)

Mass and Weight

Mass = the mass of an object / body is the amount of matter contained in it. Weight  = -The weight of a body is the force with which the Earth pulls the object towards the centre of the Earth - Weight = Mass * Gravitational Force Gravitational Force of Earth is approximately 10 meters per second squared. SI Unit of Weight is the NEWTON (N)
