What is the unit for force?
Newtons (N)
distance traveled divided by time taken to travel that distance
What is speed?
an object in motion stays in motion and an object at rest stays at rest unless acted upon by an unbalanced force
What is Newton's first law?
What is a push or pull exerted on an object in order to change the objects position?
What is force?
Energy in motion
What is kinetic energy?
A force applied to a wooden board is 10N. If the force of friction resisting the student's push is 4N, what is the net force acting on the board?
What is 6N?
the speed of an object and in what direction
What is velocity?
Newton's second law of motion
What is F=ma? Net force is equal to force times acceleration
Combined force that does not cause an object to move
What is a balanced force?
Stored energy
What is potential energy?
Why do people jerk forward when a driver pushes the brakes suddenly?
What is Inertia? What is Newton's first law?
The change in speed or direction
What is acceleration?
Newton's third law of motion
What is action reaction? or For every action there is an equal and opposite reaction
Combined force that causes an object to move
What is unbalanced force?
Water that is behind a dam is an example of what kind of energy?
What is potential energy?
What happens if there is no force acting upon an object?
It will continue to move at the same speed in the same direction
How do you calculate velocity?
Distance divided by time and add direction

B. increase the height of the ramp
C. decrease the angle of the ramp
D. increase the friction between the ball and the ramp
A. increase the force applied to the ball.
