Question

why do we need force ?​

Answer 1

Answer:

A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate.

Force can also be described intuitively as a push or a pull.

A force has both magnitude and direction, making it a vector quantity.

Answer 2

Answer:

Forces are important because, as we learned in another lesson, they are responsible for changes in motion. In fact, Isaac Newton describes this in his first law. This law of inertia states that an object continues in its state of rest or motion unless acted on by an outside unbalanced force.
