## Difference between displacement and angular displacement

We have already discussed the difference between distance and displacement. Let us today discuss the difference between displacement and angular displacement. We will also discuss the difference between velocity and angular velocity.

## Object having zero velocity but still accelerating

We all know that acceleration is rate of change of velocity. Thus according to this definition, if the velocity of the object is zero or constant, then its acceleration will be zero. But there are certain things in life where … Continue reading

## Relation between initial velocity, final velocity and acceleration

Let us derive the relation between the initial velocity, final velocity and acceleration. Suppose a body has an initial velocity u and is moving with uniform acceleration a. Let the final velocity of the body after time t = v. … Continue reading

## Acceleration, average Acceleration, uniform Acceleration, variable Acceleration, instantaneous Acceleration

Acceleration: The state of change of velocity of a body with time is known as its acceleration. If the velocity of a body increases with time, then its acceleration is positive. On the other hand, if the velocity of a … Continue reading

## Velocity, average velocity, uniform velocity, variable velocity, instantaneous velocity

Let us discuss the definitions of velocity, uniform velocity, average velocity, variable velocity and instantaneous velocity Velocity: The time rate of change of position of a body in a particular direction is known as its velocity. Or The time rate … Continue reading

## Speed, Uniform speed, Variable speed, average speed, Instantaneous speed

Let us discuss the definitions of speed, uniform speed, variable speed, average speed and instantaneous speed in the following section: 1. Speed: The time rate of change of position of a body in any direction is known as its speed. … Continue reading

## Distance and Displacement Difference

You must have heard the terms distance and displacement. Let us discuss the difference between the two. We will also discuss the characteristics of displacement. 1. Distance: The actual length of the path covered by a body in moving from … Continue reading
