An object is in motion if its place changes with respect to a fixed point which we call the reference point.

Motion

The distance of an object to a reference point in a stated direction gives the position of the object. Position is a vector quantity which has both direction and magnitude.

Position

The change in position of an object is called displacement.

Displacement

Distance traveled in unit time is called speed.

Average speed is calculated by dividing the total distance traveled by the total time taken.

Average speed =total distance traveled

total time taken

When we talk about speed and direction, we use the term velocity.

Velocity

If an object moves with constant speed its motion is called uniform motion.

Uniform motion

Speeding Up: If an object covers more distance than

pervious second its motion is called speeding up.

Slowing Down: If an object covers less distance than

pervious second its motion is called slowing down.

Non Uniform Motion
