Which of these has the most speed and energy?

Peter sets up his toy train on the railroad tracks he has in a straight line. He has a tool to measure the speed the train is traveling in centimeters/second when he pushes it to go. He set a box at the end of the ramp for the train to crash into. He measures in centimeters how far the train pushes the box and records the data in a table.

What is Peter investigating in this experiment?

A pencil is on a teacher's desk.

Why does the pencil remain motionless and NOT fall to the ground?

Mihika and Craig are racing cars down different sloped ramps. Mihika's car traveled down Slope A and Craig's traveled down Slope B. Mihika's car traveled further than Craig's. Craig wants to beat her in the next trial. What can he do to his ramp to make his car travel further?

Katie and Gordon were experimenting with two bowling balls. One of the bowling balls had a mass of 6 kilograms, and the other had a mass of 4 kilograms. They compared the force needed to roll each of the balls at the same speed. They also compared how much force it took to stop the balls when the balls were rolling at the same speed.

Which conclusion did the students MOST likely arrive at after experimenting with both bowling balls?

Peter sets up his toy train on the railroad tracks he has in a straight line. He has a tool to measure the speed the train is traveling in centimeters/second when he pushes it to go. He set a box at the end of the ramp for the train to crash into. He measures in centimeters how far the train pushes the box and records the data in a table.

What would happen to the distance the box moves if the train increases in speed?

Glen and his friends Liam and London are going sledding at a local park. There are two hills to choose from, "The Bunny Slopes," which are small hills and lots of flat surfaces, and "The Dragon," which is a steep hill and not for beginners. Glen crashes a lot, and his friends are a little nervous. If Glen were to crash into Liam and London when they were sledding, how would the crash be different on "The Bunny Slopes" than "The Dragon"?

A group of students is investigating motion using a toy car, a ramp, and a plastic cup. The students place an empty plastic cup at the bottom of a ramp. Where on the ramp should the students release the car to push the plastic cup the farthest?

Mihika and Craig are racing cars down different sloped ramps. Mihika's car traveled down Slope A and Craig's traveled down Slope B. Mihika's car traveled further than Craig's. Why did her car travel further than Craig's?

Shakira ordered two bowling balls of the same size and type. She bought one pink ball and one orange ball. Shakira rolled each ball down the same lane at the bowling alley one time while a friend used her phone timer to measure the time it took for the balls to travel to the end of the lane. After rolling both balls down the same lane one time, they noticed that the pink ball made it to the end of the lane faster than the orange ball.

Which is the most likely reason that the pink ball moved faster than the orange ball?
