True
False
When a car crashes, some of the energy is transferred by heating.
True
False

How high will the ball bounce when dropped from twice the height?
Almost twice as high as before
The same height as before
Half as high as before
It will not bounce at all
What happens to the ball's energy when it bounces?
All the energy remains with the ball
Some of the energy is used up
Some of the energy is transferred to the concrete
All of the energy is lost
When objects collide, energy is transferred in different ways.
When an asteroid hit the Earth many millions of years ago, energy was NOT transferred by
heating
sound
electricity
pushing the Earth
Imagine two identical tennis balls moving on the floor toward each other.
Both balls are moving at the same speed (quickly) toward each other.
What will you see when they collide?
Both balls will bounce off each other
Both balls will stop immediately
One ball will stop and the other one will bounce off
One ball will bounce over the other one and carry on moving
A red car crashes into the back of a blue car, which then hits a stop sign and bends it.
Where does the energy from the red car go?
All the energy from the red car is transferred to the blue car
All the energy from the red car is transferred to the stop sign
All the energy from the red car stays with the red car
The energy from the red car is shared between the red car, the blue car, the stop sign, the ground, and the air
Consider what would happen to the egg if an Egg Racer were to hit a solid object (like a wall), while going as fast as possible. What would the collision affect?
Only the car bumper
Both the car and the wall
The car, the wall, and the egg
Only the egg
In a collision between an Egg Racer moving quickly and a wall, what would be the worst thing that could happen to the egg?
The egg would remain sitting on top of the car
The egg would bounce off the car and roll away safely
The egg would be knocked off the car, hit the ground, and smash
The egg would spin around on top of the car for a while

Position A
Position B
Position C
Position D
Which things in this picture have energy?
The man, the sun, and the cactus
The man, the sun, the car, the gasoline in the pump, and the cactus
The sun and the cactus
The sun and the man
Model toy cars can be made to move by air escaping from inflated balloons.
What would make the car go faster?
Putting wider wheels on the car
Blowing up the balloon less
Blowing up the balloon more
Using a longer tube for the air to come out of the balloon
Model toy cars can be made to move by air escaping from inflated balloons.
What would make the car go farther?
Putting wider wheels on the car
Blowing up the balloon less
Using a longer tube for the air to come out of the balloon
Putting the car at the top of a ramp and then releasing it
Engineers are starting to use virtual dummies of humans to test out safety features in cars. Which of these is NOT a reason engineers prefer to use virtual models?
They can sit in comfort at their computer to do the test
Doing the same tests with humans would be dangerous
They can work out possible injuries on the driver and passengers
They can do repeat tests
