Ann [662]

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.

What helps oxygen to be observed rapidly into the blood in the lungs ​
julsineya [31]
