The combination of all the forces acting on an object.
What is Net 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 Newton's First Law
100
The speed and direction of a moving object.
What is Velocity
100
The force that causes Earth to orbit the Sun and the Moon to orbit Earth.
What is Gravity
200
Acts in the direction opposite to the motion of the object.
What is Sliding Friction
200
A push or pull
What is Force
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 Newton's Second Law
200
A situation of state of affairs that doesn’t change.
What is Constant
200
When air resistance balances the force of gravity, the object falls at a constant speed.
What is Terminal Velocity
300
Occurs when an object rolls across a surface.
What is Rolling Friction
300
When the net force is not zero
What is Unbalanced Forces
300
Forces always act in equal but opposite pairs.
What is Newton's Third Law
300
An object is the size of the gravitational force exerted on an object.
What is Weight
300
The tendency of an object to resist a change in its motion.
What is Inertia
400
The type of friction that prevents an object from moving when a force is applied.
What is Static Friction
400
Two or more forces exerted on an object, and if there effects cancel each other and they do not change the object’s velocity.
What is Balanced Forces
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 Newton's Second Law
400
The tendency of an object to resist a change in its motion.
What is Inertia
400
Two or more forces exerted on an object, and if there effects cancel each other and they do not change the object’s velocity.
What is Balanced Forces
500
Acts in the direction opposite to the motion of the object.
What is Sliding Friction
500
When an object moves in circular motion, the net force on the object.
What is Centripetal Forces
500
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 First Law
500
The amount of matter in an object
What is Mass
500
The combination of all the forces acting on an object.
