A plane flying from Austin to Dallas makes the 192 mile trip in 1
hour. This is its velocity.
What is 192 miles/hour North?
Back to you Alex 200200
What are speed up, slow down, and change direction?
Back to you Alex 300300
The 3 ways that an object can accelerate.
The speed of the athlete in the graph below
What is 10 meters per
second?
Back to you Alex 400400
(s)
The section of the graph that represents moving at a constant
velocity
What is section a?
Back to you Alex 500500
The definition of force.
What is a push or a pull?
Back to you Alex 100100
Back to you Alex 200200
You might add sand to an icy driveway to increase the force of
this.
What is friction?
Back to you Alex 300300
The type of forces acting on the box below.
What are unbalanced forces?
5 N 10 ND
The definition of inertia
What is the tendency of an object to resist change in its motion?
Back to you Alex
Daily Double

The more of this an object has, the more inertia it will have.
What is mass?
Back to you Alex 500500
Newton’s 2nd law says that force equals this.
What is mass x acceleration?
Back to you Alex 100100
Back to you Alex 200200
Newton’s 1st law says this.
What is an object at rest will stay at rest, and an object moving with a constant
velocity will continue moving with that constant velocity, unless acted on by an
unbalanced force?
Back to you Alex 300300
According to Newton’s 2nd law, in order to increase the acceleration of
an object, you must do this.
What is increase the amount of force you use OR decrease the mass of the object?
Back to you Alex 400400
The law and explanation for why we seem to lift out of our seat when a rollercoaster car goes down a hill.
What is Newton’s 1st law because our body is at rest at the top of the
hill and tends to want to stay at rest until acted on by an unbalanced
force?
Back to you Alex 500500
What is Newton’s 3rd law because you exert a force on the
volleyball (volleyball flies away) and the volleyball exerts an equal force on you (your hand stings)?
The law and explanation for why when you hit a volleyball, the
volleyball flies away from you and your hand stings.
The force that you exert on the machine.
What is input force?
Back to you Alex 100100
Back to you Alex 200200
The simple machine that is an inclined plane wrapped around a
cylinder.
What is a screw?
Back to you Alex 300300
The 3 ways that a simple machine can make work easier.
What are decrease amount of input force needed, spread the force out over a greater
distance, and change the direction of the force?
Back to you Alex 400400
Of the 3 ways machines can make work easier, a 3rd class level makes
work easier by doing this.
Daily DoubleWhat is multiplying your input force (or decreasing the amount of force needed)?
3rd class lever
Baseball bat
The type of pulley that you would use if you wanted to decrease the
amount of force needed and change the direction of the force.
What is a multiple pulley system?
Back to you Alex 500500

Stored energy.
What is potential energy?
Back to you Alex 100100
The definition of kinetic energy.
What is energy of motion?
Back to you Alex 200200
Of a skateboard, a ball, or a person—the one that has the greatest potential energy at the top of a
staircase.
What is a person?
Back to you Alex 300300
