Question

Define the following:(i) Variable acceleration​

Answer 1

Answer:

• A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.
• Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. ... Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Answer 2

Answer:

If the average acceleration is different between different points along its path, either in magnitude or in direction or both in magnitude and direction then the body is said to be moving with variable acceleration. And also velocity changes at each interval of time by decreasing or increasing by equal amount.
