If a car drives 500 km in 10 hours, this is its speed.

What is 50 km/hr?

Back to you Alex 100100

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

400400

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

Fixed MoveableMultiple Pulleys

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

The letter representing the point where the rollercoaster has the

greatest kinetic energy

What is X?

Back to you Alex 400400
