Acts on an object at rest sliding friction slows down that object that slides
What is Sliding friction
100
If the net is not zero
What is Unbalance forces
100
Amount of matter in an object
What is Mass
100
If the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed
What is Newton’s 1st Law
200
The speed and direction of an moving object
What is Velocity
200
When an object rolls across a surface
What is Rolling friction
200
To or more forces exerted on an object
What is Balanced forces
200
Exist in any object that has matter. Has gravitational pull it attracts and pulls objects toward each other
What is Gravity
200
The acceleration of an object equals the net force divides by the mass and is in the direction of the net force
What is Newton’s 2nd Law
300
Occurring constantly over time
What is Constant
300
Is caused by the attraction between the atoms on the two surfaces that are on contact
What is Static friction
300
When more than one force act on a object is net force
What is Net force
300
Air resistance balances the force of gravity, the object falls at a constant speed
What is Terminal velocity
300
Forces that always act in the equal but the opposite pairs
What is Newton’s 3rd Law
400
Of an object is the size of the gravitational force exerted on an object
What is Weight
400
By sliding or rubbing on another object
What is Friction
400
A push or pull
What is Force
400
Is the point in an object that moves as if all the objects mass were concentrated at that point
What is Center of mass
400
Exist in any object that has matter. Has gravitational pull it attracts and pulls objects toward each other
What is Gravity
500
The tendency of an object to resist a change in its motion
What is Inertia
500
When an object moves into a circular force
What is Centripetal force
500
The speed and direction of an moving object
What is Velocity
500
If the net is not zero
What is Unbalance forces
500
I the point in an object that moves as if all the objects mass were concentrated at that point
