WebJul 3, 2024 · First Rule: An object will remain at rest or in a uniform state of motion unless that state is changed by an external force. Second Rule : Force is equal to the change in momentum (mass times velocity) over time. In other words, the rate of change is directly proportional to the amount of force applied. Third Rule: For every action in nature ... WebCentripetal acceleration is defined as the property of the motion of an object traversing a circular path. Any object that is moving in a circle and has an acceleration vector pointed towards the centre of that circle is known as Centripetal acceleration. You must have seen various examples of centripetal acceleration in your everyday life.
