$100 Type of motion described in the chart below. TimeChange in Distance 1 minute3 meters 2 minutes3 meters 3 minutes3 meters 4 minutes3 meters

Return $100 What is a constant rate of change?

$200 What we call the time it takes an object to move a certain distance.

Return $200 What is speed (or velocity if it is in a particular direction)

$300 Motion seen in the following diagram.

Return $300 What is acceleration or speeding up?

$400 Joe’s speed if he traveled 1200 km in 4 hours.

Return $400 What is 300 km per hour?

$500 When thrown straight up in the air, the speed of a ball at its highest point.

Return $500 What is 0 meters per second?

$100 Scientific name for a push or a pull.

$100 What is a force? Return

$200 The force that pulls objects towards Earth’s center (or toward each other).

Return $200 What is gravity?

$300 How forces are described when they equally push or pull in all directions causing no movement.

Return $300 What is balanced?

$400 The direction the object would move if these were the forces:

Return $400 What is to the right?

$500 Factor that slows an objects that are touching one another.

Return $500 What is friction?

$100 Property that says that an object in motion or at rest will remain that way unless another force acts upon it.

Return $100 What is inertia?

$200 The explanation why a train moving at 100mph is more difficult to stop than a ball moving at 100mph.

Return $200 What is momentum?

$300 This is reduced between a car and the road if the road is covered with ice.

$300 What is friction? Return

$400 Source of energy used to move a sailboat.

Return $400 What is wind or moving air?

$500 This is where the friction is that will slow a sailboat to a stop.

Return $500 What is between the boat and the water?

$100 The simple machine that would best be used to cut a rope.

$100 What is a wedge? Return

$200 The simple machine that would be best be used to open a door.

Return $200 What is a wheel and axle (the door knob)?

$300 The simple machine shown below:

Return $300 What is an inclined plane?

$400 The simple machine shown below (not the staples):

Return $400 What is a lever?

$500 A simple machine that reverses the direction of effort and is usually used to lift or lower objects.

Return $500 What is a pulley?

$100 Putting wheels under an object, this is often reduced.

Return $100 What is friction?

$200 Two kids are each wearing roller skates. One pushes the other and both move away from each other. This is Newton’s Law that explains this.

Return $200 What is Newton’s Third Law (equal and opposite reaction)?

$300 This is what all machines need in order to do work.

Return $300 What is energy (or a power source)?

$400 As in this picture, Newton’s Law that explains why the bike should continue to move in a straight path.

Return What is Newton’s First Law (Law of Inertia)?

$500 What is needed for an object to move.

Return $500 What is an unbalanced force?

Make your wager- How much are you willing to risk? Minimum is $0, maximum is the total of what you have!

The difference between acceleration and velocity.

Return What is velocity is the speed of an object in a certain direction, but acceleration is a change in velocity?
