Moduel 1 Test Flashcards
Newton’s third law of motion
When the 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
Gravity
An attractive force that exists between all objects that have mass
Acceleration
A measure of the change in velocity over a period of time
Vector
A quantity that has both direction and magnitude
Velocity
The speed and direction of a moving object
What do larger arrows indicate
A larger force
Displacement
The difference between the initial, or starting position and the final position
Speed
A measure of the distance an object travels in a given amount of time
Elastic collision
When colliding objects bounce off each other
Force pair
The force 2 objects apply to each other
Newton’s second law of motion
The law states that the acceleration of the object is equal to the net force exerted on the object, divided by the objects mass
Normal force
The force that pushes perpendicular to the objects surface
Motion
The process of changing position
Contact force
A push or a pull on a object by another object that is touching it
How is net force calculated
Net force is calculated by adding together the forces acting in the same direction, and subtracting the forces acting in the opposite direction
