Definition 1: Newton’s first law of motion
An object continues in a state of rest or uniform motion (motion with a constant velocity) unless it is acted on by an unbalanced (net or resultant) force.
- Definition 2: Newton’s second law of motion
If a resultant force acts on a body, it will cause the body to accelerate in the direction of the resultant force. The acceleration of the body will be directly proportional to the resultant force and inversely proportional to the mass of the body. The mathematical representation is:F⃗ net=ma⃗
Definition 3: Newton’s third law of motion
If body A exerts a force on body B, then body B exerts a force of equal magnitude on body A, but in the opposite direction.
