An Introduction to Displacement
Displacement is the change in the position of any point or object. It has a direction and magnitude, so it is a vector quantity. It is shown with an arrow that points from the starting position to the final position. For example, an object moved from position A to position B, then the position of…

Things to Remember
At the atomic level, when atoms or molecules are pulled apart from each other and gain potential energy with a restoring force still existing, the restoring force might create tension. Each end of a string or rod under such tension could pull on the object it is attached to, in order to restore the string/rod…

What is Tension Force?
In Latin, the word “tension” means “stretching”. The force which is applied to the length of a flexible area such as a rope or a cable, or chain is referred to as tension formula force in physics. We know that a push or pull is indicated by a tension force. In physics, we are dealt…

How to Calculate Tension Force
Tension refers to the pulling force transmitted axially by the means of a string, cable, chain, or similar one-dimensional continuous object, or by each end of a rod, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of the said elements.

Angular Acceleration Formula
The rate at which the angular velocity changes with time is known as the angular acceleration in circular motion. It is also known as rotational acceleration. The quantity has both magnitude and direction, so it is a vector quantity. Angular acceleration is denoted by α. Let θ be the angular displacement, ω� be the angular…

Angular Acceleration Unit
As the acceleration vector is perpendicular to the plane where the rotation occurs, the acceleration vector is perpendicular to that plane. An acceleration velocity that points away from the observer is created by increasing angular velocity clockwise. The vector of angular acceleration points to the viewer if the increase in angular velocity is counter clockwise. …

What is Angular Acceleration?
Time rate of change in angular velocity is defined as angular acceleration. Radians per second per second is a common unit of measurement. Hence, α=dωdt�=���� Also known as rotational acceleration, angular acceleration occurs when a body rotates. An angular velocity change per unit of time can be expressed as a quantitative vector. A pseudo scalar…

Equation & Solved Examples
Acceleration is caused by varying velocity. We call it angular acceleration if an object is spinning and changing its speed. Let us explore angular acceleration in detail in this article. Example 1 If the angular velocity of a body in rotational motion changes from π2�2rad/s to 3π43�4 in 0.4 s. Find the angular acceleration. Solution:…
