** ****KINEMATICS (MOTION SPEED VELOCITY) CHEAT SHEET**

**Distance: *** Distance* is a scalar quantity representing the interval between two points. It is just the magnitude of the interval.

**Displacement:** * Displacement* can be defined as distance between the initial and final point of an object. It is a vector quantity having both magnitude and direction.

** **

**Displacement is zero**

**Distance taken is=lABl+lBCl+lCAl**

** **

**Speed: ****Speed** can be defined as “how fast something moves” or it can be explained more scientifically as “the distance covered in a unit of time”. Speed is a scalar quantity.

** **

**Velocity: **It can be defined as “speed having direction” or displacement in a unit of time. Velocity is a vector quantity and it has both magnitude and direction.

** **

**Acceleration: **We can easily define ** acceleration **as “change in velocity”. This change can be in the magnitude (speed) of the velocity or in the direction of the velocity.

**Equations of Linear Motion**

**Free Fall: **Motion of an object dropped from a height without initial velocity. Only force acting on an object is its weight or gravitational force. Equations of free fall;

**V=g.t**
