|
Sometimes reffered to as the Law of Inertia.
An object will not change its motion unless a firce acts on the object.

|
Term
| Newton's 2nd Law of Motion |
|
Definition
|
A net force acting on an object changes the velocity of the object, causing acceleration.
The acceleration depends on the mass of the object.
More massive objects need more force to change motion.

|
Definition
|
Sometimes referred to as Action-Reaction.
When an object exerts a force on another object, the second object exerts an equal force in the opposite direction.
