Speed, Velocity & Acceleration

Speed is how fast you are going and how far you travel in a certain time.

Stationary Object

Distance-time graph provides useful information about the motion of an object.

A speed–time graph has the same idea as given in the distance–time graph but different quantities are plotted on the y-axis.

Formula of the acceleration is given by the following equation.

Acceleration due to Gravity

The acceleration due to gravity is a constant rate of acceleration.

When the object is first released from a certain height, under the effect of gravity, the only force acting upon it is its own weight. It accelerates downwards with acceleration due to gravity.
