QuestionAnswer
intertia an object's ability to resist any change in motion
Acceleration A measure of the change in velocity during a period of time.
Contact force A force or a pull on one object by another object that is touching it.
Newtons 1st Law An object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object.
Newtons 2nd Law Law that states that the acceleration of an object is equal to the next force exerted on the object divided by the object's mass.
Newtons 3rd Law When an object applies a force on another object, the second object applies a force of the same strength on the first object but the force is in the opposite direction.
Friction A contact force that resists the sliding motion of two surfaces that are touching.
Free-body diagram A simple model to understand what will happen to an object due to a force.
Force A push or pull on an object
Net-Force The combination of all the forces acting on an object.
Motion The process of changing position.
Displacement The difference between initial, or starting, position and the final position.
Speed A measure of the distance an object travels in a given amount of time.
Velocity The speed and the direction of a moving object.
Vector A quantity that has both magnitude and direction
Reference point The starting point you choose to describe the location, or position, of an object.
Position An object's distance and direction from a reference point.
Force pair The forces two objects apply to each other.
Normal force The force that pushes perpendicular to the objects surface.
Elastic collision When colliding objects bounce off each other.
Inelastic collision When colliding objects stick together.
Gravity An attractive force that exists between all objects that have mass.
Field A region of space that has a physical quantity at every point.
Non-contact A force that one object can apply to another object without touching it.
Weight The gravitational force exerted on an object.
