➔ A force is a push or pull on an object
➔ Force is measured in Newtons (N)
➔ The Newton is named after Issac Newton, in recognition of his work in mechanics.
EFFECTS OF FORCE
● Change in shape → Deformation
● Change in motion
➔ If an object is stationary, a force can cause the object to start moving.
➔ If the object is already moving, a force can make an object speed up or slow down.
● Change in direction
MOTION OF THE OBJECT
Velocity is the rate of change of the position of an object.
➔ The speed of an object and the direction in which it is moving
➔ Speed describes how fast an object is moving.
An object can move at a constant velocity, meaning it travels at the same speed in the same direction.
The Velocity of an object is changing over time due to force acting on it. → Acceleration.
