the distance an object moves in a certain amount of time
What is speed?
100
When you are in a car, you should always wear a seat belt. This science term described by Isaac Newton explains why you could fly forward if the car stops suddenly.
What is inertia?
100
The force that works against motion to slow things down
What is Friction?
100
how you know the highest interval of speed on a graph
What is the steepest part of the line?
200
Forces that act on an object will NOT make the object move if all the forces are ___________________.
What is balanced?
200
The speed of an object in a particular direction.
What is velocity?
200
You push a soccer ball with a certain amount of force. You push a bowling ball with the same amount of force. This is the reason the soccer ball will travel farther.
What is less mass requires less force to move?
200
a way to reduce friction

Calculate the speed of a dog running through a field if he is covering 23.7 meters in 54 seconds.
What is .44m/s?
300
In circular motion, this force is always causing objects to move toward the center.
What is centripetal force?
300
a change in a moving object’s speed or direction
What is acceleration?

This happens when a rocket's force pushes downward.
What is accelerates upward?
400
The SI (metric) unit scientists use to express force.
What is a Newton?
400
you need this information to calculate acceleration
What is starting and ending velocities and the time it took?
400
An example of this law is the downward force of a rocket's boosters blasting the rocket up off the launch pad.
What is Newton's third law?
400
Rougher surfaces will provide an _________________ in friction.
What is increase?

Two tugboats are moving a barge. Tugboat A exerts a force of 3000 newtons on the barge. Tugboat B exerts a force of 5000 newtons in the same direction. What is the net force on the barge?
What is 8000 N?
500
When the net force on an object is NOT 0 N.
What is an unbalanced force?

Less force (or mass) will provide an __________________ in friction.
What is decrease?
500
Now suppose that Tugboat A exerts a force of 2000 newtons on the barge and Tugboat B exerts a force of 4000 newtons in the opposite direction. What is the combined force on the barge?
