Q:

# What are the three types of acceleration?

A:

In physics, the three types of acceleration are changes in speed, direction and both simultaneously. The word "velocity" is often used in place of speed. A person can calculate the acceleration of an object by determining its velocity and the length of time it accelerates.

When a car makes a sudden turn, it experiences an increase in acceleration, even if its speed remains constant. This increase in acceleration can be felt through the jerking effect that is imposed on the passengers' bodies. In addition to regular acceleration, an item can experience negative acceleration, which is characterized by a decrease in speed. The intended direction of an object may remain positive regardless of its velocity rate.

More than three types of energy exist, but a few examples of energy types include mechanical, heat and electrical energy. These describe the energy of motion that does work, the energy of being pushed into motion by heat and the energy when electricity creates motion, light and heat.

Speed and velocity are similar in that they are measured in the same measurement units, which are meters per second. However, velocity and speed are very different quantities because one has a direction and the other one does not.
