Name That Word!
What word means an object is not moving?
Stationary
A rolling ball knocks over a cup. Which object gives motion energy to the cup?
The rolling ball
A bowling ball hits standing pins. What might happen to the pins?
They may fall over
Car A moves a block 6 cm. Car B moves it 18 cm. Which car transferred more energy to the block?
Car B
A moving ball has motion energy. True or false?
True. Moving objects have motion energy.
What do we call a change in an object’s position?
Motion
A moving foot kicks a resting soccer ball. Where does energy transfer—from the foot to the ball or from the ball to the foot?
From the foot to the ball
A moving toy car hits a resting toy car. Why might the resting car begin moving?
It receives motion energy from the moving car.
A slow car moves a block 4 cm. A faster identical car moves it 15 cm. Which speed caused greater energy transfer?
The faster speed!
A collision can transfer energy to a resting object. True or false?
True. The resting object can receive energy and begin moving.
What type of energy does a moving object have?
Motion energy
A moving racket hits a tennis ball. Which object receives energy from the racket?
The tennis ball
A ball hits a cardboard tube and makes it roll. What observation shows that energy transferred?
The tube begins rolling after being hit.
Truck P moves a block 22 cm. Truck Q moves it 9 cm. What evidence supports the claim that Truck P transferred more energy?
The block moved farther: 22 cm instead of 9 cm.
Motion energy always transfers from standing bowling pins to the rolling ball that knocks them over. True or false?
False. Energy transfers from the rolling ball to the pins.
What do we call the event when two objects hit each other?
Collision
A rolling marble hits a resting marble. Which marble receives motion energy during the collision?
The resting marble
A moving marble hits a resting marble and slows down. What happened to some of its motion energy?
Some transferred to the other marble.
The same car moves a block 5 cm, 12 cm, and 21 cm as its speed increases. What pattern do you notice?
As speed increases, the block moves farther, showing greater energy transfer.
When a moving object slows down during a collision, its energy is destroyed. True or false?
False. Energy transfers or changes form; it is not destroyed.
What do we call energy moving from one object to another?
Energy Transfer
A moving toy truck hits a resting block. Describe the direction of energy transfer.
From the moving truck to the block
A toy truck hits a block, but the block does not move. Is the block’s lack of movement enough to prove that no energy transferred?
No. Energy can transfer without visible movement, such as into sound or thermal energy.
Two identical cars hit the same block in separate tests. One moves it farther. A student says they transferred equal energy because they hit the same block. Does the evidence support the claim?
No. The greater distance supports greater energy transfer.
If both objects eventually stop moving after a collision, no energy was transferred. True or false?
False. Energy can transfer during the collision even if the objects later stop.
