Yikes! You almost knocked me down! This box of cargo had too much energy. Both height and force give the box more potential energy.
What Happened?
When you lift the box higher in the air, you give it more potential energy. Gravity gives an object more weight and pulls it toward the Earth’s surface. Then, the energy that an object has when it is moving (its kinetic energy) decides how far it goes before gravity brings it to the ground. Learn more about energy.
Although this cliff is higher than the last one, you may not need to lift this box of cargo up so high or give it such a hard shove to swing it across.
Oh no! This box of cargo didn’t have enough energy to make it across the canyon.
What Happened?
Remember, this cliff is higher than the last one, so the box of cargo needs more energy to travel the distance. You can give an object more potential energy by lifting it higher in the air. However, the rock overhang gets in the way of lifting the box of cargo high enough. You can make up the difference in the height by using additional force to push it. The force and the height both increase the box’s energy to make it across the canyon. Learn more about energy.
Next time, try lifting this box up higher or giving it a harder push to swing it across the canyon.
Yay! You figured out the right amount of energy to send this box of cargo over to me.
What Happened?
You came up with the right combination of height and force to get the cameras safely across this higher canyon.
Let’s move the rest of the boxes.
Great! It’s time to move ahead. Bring on the next canyon!
What Happened?
This next canyon is even higher than the last one. Our rope is about to break so we need to combine two of the boxes into one. Remember everything you learned about weight, height, and energy to get these boxes across this final canyon.
Move on to Level 3!
