EVERYDAY SCIENCE

Detailed explanation-1: -Answer and Explanation: An object accelerates when its velocity changes. Velocity is both an object’s speed and the direction in which it is traveling, so acceleration can be either the change in an object’s speed (getting faster or slower) or the change in its direction.

Detailed explanation-2: -Acceleration is defined as the rate of change of velocity. This means that if an object’s velocity is increasing or decreasing, then the object is accelerating. Unlike an object moving at a constant velocity, an accelerating object will not have a constant change in position every second.

Detailed explanation-3: -Objects can accelerate, or change their rate of velocity, in one of three ways. They can accelerate as a result of a change in speed. They can accelerate in response to a change in direction. Finally, they can accelerate as a result of changes in both speed and direction.

Detailed explanation-4: -Can an object accelerate if it’s moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object-even if the object is maintaining a constant speed-still count as acceleration.

Detailed explanation-5: -There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
