**KINEMATICS CHEAT SHEET**

**Distance:**

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

**Distance**

**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**

Displacement is zero

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.**

**All aspects of free fall are the same as horizontal motion, just in the vertical position, and with**

*g*as*a*.**Relative Motion:**

**When different objects are moving in relation to each other, their motions must be seen as a whole, and often, relative velocities will overlap. This is often in the form of vector quantities.**
