What is Newton’s first law of motion?
Every body at rest tends to remain at rest, whereas every body in motion tends to remain in motion, unless it is acted upon by an unbalanced external force.
What is Newton’s second law of motion?
The acceleration of any body is directly proportional to the force acting on the body, whereas it is inversely proportional to the mass of the body.
What is another way to write Newton’s second law of motion?
F=Ma
What is Newton’s third law of motion?
For every force exerted on a body by another body, there is an equal but opposite force reacting on the first body by the second
