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
100
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 2nd Law
100
The weight of an object is the size of the gravitational force exerted on an object.
What is Inertia
100
The direction of the centripetal force is toward the center of the object’s circular path.
What is Centripetal Force

Whats my middle name?
What is I don't have one!
200
forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction.
What is Newton's 3rd Law
200
The combination of all the forces acting on an object
What is Net force
200
Rolling friction occurs when an object rolls across a surface.
What is Rolling Friction
200
When the air resistance force equals the weight, the net force on the object is zero.
What is Terminal Velocity
200
What time was I born?
What is 11:11
300
A push or a pull.
What is Force
300
The force that brings nearly everything to a stop is friction, which is the force that acts to resist sliding between two touching surfaces.
What is Friction
300
sliding friction acts in the direction opposite to the motion of the box.
What is Sliding Friction
300
The center of mass is the point in an object that moves as if all the object’s mass were concentrated at that point.
What is Center of Mass
300
how many cats have i had in my whole life?
What is 5

If the forces on an object are balanced, the net force is zero. If the net force is not zero, the forces are unbalanced forces.
What is Unbalance Forces
400
the speed and direction of a moving object
What is Velocity
400
The type of friction that prevents an object from moving when a force is applied is called static friction.
What is Mass
400
the change in velocity divided by the time over which the change occurred
What is Acceleration

What is my favorite sport?
What is Tennis
500
not changing or varying
What is Constant
500
Two or more forces exerted on an object are balanced forces if their effects cancel each other and they do not change the object’s velocity.
What is Balanced Forces
500
The force of gravity exists between any two objects that have mass. Gravity always is attractive and pulls objects toward each other.
