The force that brings nearly everything to a stop.
What is Friction?
100
The point in an object that moves as if all the object’s mass were concentrated at that point.
What is Force?
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 Newtons 1st Law?
100
The speed of something in a given direction.
What is Velocity?
100
The force that causes Earth to orbit the sun and the moon to orbit Earth.
What is Gravity?
200
While static friction acts on an object at rest, sliding friction slows down an object that slides.
What is Sliding Fiction?
200
If the net force is not 0.
What is Unbalanced Forces?
200
The acceleration of an object equals the net force divided by the mass and is in the direction of the net force.
What is Newtons 2nd Law?
200
Occurring continuously over a period of time.
What is Constant?
200
If its speed is constant due to the restraining force exerted by the fluid through which it is moving.
What is Terminal Velocity?
300
Slow down and eventually stop because os another type of frictional source.
What is Rolling Friction?
300
Two or more forces exerted on an object.
What is Balanced Forces?
300
Forces always act in equal but opposite pairs.
What is Newtons 3rd Law?
300
Size of the gravitational force exerted on an object.
What is Weight?
300
The point of an object that moves as if all the object’s mass were concentrated at that point.
What is Center Of Mass?
400
When you push something at first and it eventually moves.
What is Static Friction?
400
The combination of all the forces acting on an object.
What is Net Force?
400
The acceleration of an object equals the net force divided by the mass and is in the direction of the net force.
What is Newtons 2nd Law?
400
The tendency of an object to resist a change in motion.
What is Inertia?
400
Equals the net force divided by the mass and is in the direction of the net force.
What is Acceleration?
500
While static friction acts on an object at rest, sliding friction slows down an object that slides.
What is Sliding Fiction?
500
Any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path.
