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"?

When Glen sleds down both of these hills, he will be traveling at a speed relative to the slope of the hill and gravity's pull. "The Dragon" is a much steeper and longer decline, so Glen will have more time to gain speed, which means more energy behind the collision. If Liam and London are down at the end of the slope and Glen crashes into them, the force will drive both of their sleds forward and slow or stop Glen's sled. The faster Glen is going, the more energy he has behind the impact.

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?

Tap to reveal answer
Peter’s investigation was testing how the distance a box moved would change as the speed of a toy train increased or decreased. The pattern within the data table shows that the higher the rate of the train, the further the box moved. An inference can be made that the higher something’s speed is, the more energy it has. Higher amounts of energy will result in a more significant change of motion for the object it is acting on. When the speed decreases, the distance the box moves also decreases. There is a direct relationship between speed and energy. So if he were to increase the speed of the train, the box would move a longer distance.

Tap to reveal answer
Mihika's car traveled further than Craig's and the children are wondering why this happened. Mihika has a very steep slope to her ramp which allows her toy car to travel faster and further. The more speed that the car can generate the more energy it has, this will allow the car to move further.

Tap to reveal answer
Mihika's car traveled further than Craig's because her ramp was steeper. This allowed her car to gain more speed and gravity to have more of a pull on the vehicle. More energy and speed will enable the car to travel faster and further. If Craig makes his ramp steeper, he will have a chance of beating Mihika in the next trial. In theory, if his ramp is steeper than Mihika's, he should be able to gain more speed and more energy so the car will 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?

When the speed decreases, the distance the object moves also decreases. There is a direct relationship between speed and energy. If the car is placed at the top of the ramp, it will have more force exerted on it from gravity pulling it towards the ground, more room to gather speed, and the steeper incline would allow for more force to be transferred to the plastic cup, therefore, moving it a further distance.

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.
