Sandy and Annie are playing mini-golf. Annie begins by swinging hard and hitting the ball with a strong blow. Then Sandy swings softly at the ball, giving it a light tap.
How is the effect of a hard push on the ball different from a soft push?
A hard push moves the ball more slowly and in only one direction.
A hard push moves the ball more slowly and over less distance.
A hard push moves the ball faster and in different directions.
A hard push moves the ball faster and farther.
Imagine you are bowling with family and it's your turn. You roll the bowling ball and hit all the pins! STRIKE! What occurred when the bowling ball hit the pins?
energy loss
energy transfer
collision
deceleration
How can the energy from a pin cause motion or change?
the pin can create motion by generating heat energy
the pin causes change by absorbing light energy.
the pin moves by using electrical energy directly.
if the pin falls it could hit another pin, causing it to hit another, and it keep going until they all fall down
Sam and Betsy are trying to win a prize at the fair by throwing beanbags at cans. Sam’s tosses always strike a can, but they do not knock it over.

kinetic
potential
At which point on a roller coaster will the cart experience kinetic energy?
at the top of the hills
going down the hills
If both books are knocked off, which book will have more kinetic energy and why?
Book A will have more energy because it's on a shorter table.
Book B will have more energy because it's on a taller table.
Book A will have more energy because it's on a taller table.
Book B will have more energy because it's a smaller book.
Which describes the energy transformation that will occur if someone knocks over one of the books from the table.
The book has potential energy until it's knocked off, which will turn into kinetic energy.
The book has kinetic energy until it's knocked off, which will turn into potential energy.
