Question
Kinetic energy is transferred from a bowling ball to a bowling pin, causing the pin to fly away at a much higher speed than the bowling ball. What does this tell you about the bowling pin?(1 point)
The pin has much less kinetic energy than the bowling ball.
The pin has a much lower mass than the ball.
The pin has a much higher mass than the ball.
The pin has more kinetic energy than the bowling ball.
Why is a small car less safe in a collision with a large truck?
When kinetic energy is transferred, it will have a greater effect on the car that has _____ (1 point)
less velocity.
less mass.
more kinetic energy.
less friction.
A billiard ball collides with another billiard ball, transferring all of its kinetic energy. What will happen after the collision?(1 point)
The second ball will come to a stop, just like the first ball.
The second ball will move away at the same speed because it has the same mass.
The second ball will move away at half the speed because the kinetic energy is divided between the two balls now.
The second ball will move away twice as fast because it has the kinetic energy from both billiard balls.
A heavy weight is resting on a mattress. A much lighter weight is dropped onto the mattress, and the larger weight moves slightly. How can this be explained?(1 point)
The small mass transferred a large amount of kinetic energy to the large mass, making it move slowly.
The large mass absorbed the kinetic energy rather than moving.
The small mass transferred a small amount of kinetic energy to the large mass, making it move slowly.
The small mass kept its kinetic energy rather than transferring it to anything.
The pin has much less kinetic energy than the bowling ball.
The pin has a much lower mass than the ball.
The pin has a much higher mass than the ball.
The pin has more kinetic energy than the bowling ball.

dont use his answers there gonna get you a 40
than whats the answer
Yoo bruvs what are the correct answers??
Aight I'm finna take the test and I'll be back to tell you the correct answers
My questions were out of this order so I'm not going to put the letter.

You are right I checked your answers
Lynn is right guys. Thanks :)
Anonymous is 100% correct thank you so so much 😘
Thank you Lynn! I got a 100%
Lyn is right!
Lynn is right 4/4!!! Thxxx- even for connexus
Lynn is correct!
You took one for the boys!
You took one for the boys!
lynn is right
What was her answer? I just saw questions so I'm confused
Nevermind I got it
Thank you @Lynn, you are 100% correct
Lynn and anonymous are correct they put the same answer's follow there answers there correct
Lynn thxs soooooo much
Anonymous is right
Thanks Lynn! I got 100% 4/4!!!!!!!!!!!!!
Anonymous is correct! tysm!
thx so much lynn!!! and anonymous
correct
Yup! Thank you Lynn! You saved me!
thxxx Lynn team boys all the way👍
thx so much @lynn <3
i have five fricking questions! NOT HELPING LYNN!
The above answers are all true. Thanks Lynn!
The new quiz has 5 questions.
5) On sledding hills, there are often rules against having many people sled down at the same time together. Why is that?
Answer: If many people collided with one person, then there would be a larger transfer of kinetic energy.
I checked the answer already and this is the correct answer.

it is ok boy,s
lynn is right for connexus
Lynn is correct
Lyn is right and Nat was right about question 5
Energy of Motion Online Practice
1. What is the energy associated with the motion of an object? (1 point)
Kinetic Energy***
2. As an object falls, how are kinetic and potential energy related? (1 point)
Potential energy will decrease in an amount equal to the increase in kinetic energy.***
3. A student drops the four objects listed from a height of 2 meters into a bucket of water. Which object will have the greatest kinetic energy? (1 point)
small rock***
4. What is one way to decrease the kinetic energy of an object? (1 point)
Decrease its speed***
5. Two objects are moving at the same speed. Which one has more kinetic energy? (1 point)
The object with the greater mass***
6. A child is racing several springy toys down the stairs. Springy toys are cylinders of coiled wire that bend and flex, and can “hop” down stairs one step at a time. The child places one on the bottom stair, one in the middle of the stairs, and one on the top of the stairs. Which one has the greatest potential energy and why? (1 point)
All have the same potential energy because they are all traveling an equal distance of one step at a time***
7. In the image of the girl swinging, how is energy distributed? (1 point)
She has high potential energy and low kinetic energy.***
8. A 16-pound bowling ball strikes a 3.5-pound bowling pin. The pin is moving very fast after the collision. It has a large increase in velocity as a large amount of kinetic energy is transferred to it. Where does the energy come from? (1 point)
It is lost by the bowling ball, which would have a smaller decrease in velocity.***
9. A mother and her small child are standing in an inflatable bouncy house on opposite sides. The mother jumps up and comes back down again, transferring her kinetic energy to the child through the floor. How will the motion of the small child change? (1 point)
The child will move up at a faster speed because the child has less mass.***
10. Water moves through a hydroelectric dam. Which statement describes the changes in energy that occur? (1 point)
Energy changes from potential to kinetic to electric.***
11. Which place is the best choice for a wind farm? (1 point)
A place where the wind has more kinetic energy to convert into electrical energy.***
