What is the role of force in the motion of a body?

A force moves or tends to move, stops or tends to stop the motion of a body, and can also change the direction of motion of a body. Signup and view all the answers

What is the significance of Newton's First Law of Motion?

A body continues its state of rest or of uniform motion in a straight line provided no net force acts on it. Signup and view all the answers

What is the relationship between mass and velocity in determining the momentum of a body?

The momentum of a body is given by the product of its mass and velocity. Signup and view all the answers

What is the fundamental principle underlying the motion of an object?

The fundamental principle underlying the motion of an object is the law of inertia, which states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force. Signup and view all the answers

How does the concept of inertia relate to the motion of an object?

Inertia is the property of an object that causes it to resist changes in its motion, and it is the tendency of an object to maintain its state of rest or motion unless acted upon by an external force. Signup and view all the answers
