Answer:
Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. The greater the force that is applied to an object of a given mass, the more the object will accelerate.
Explanation:
For example, doubling the force on the object doubles its acceleration.
Example 1: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.
