Unit 7.1 Energy

Energy and energy transformations

QuestionAnswer
Ways to decrease the amount of magnetic forces pulling on two magnets use weak magnets, use opposite sides of the magnet, or move the magnets further apart.
When showing weaker forces on a model the arrows should be smaller as the distance between the magnets increase.
A car traveling down a track the kinetic energy is affected by mass and the speed of the car.
To make the water splash further from the pool the more kinetic energy the object has jumping into the pool the distance the water will splash will increase.
The slower an object moves ( the slower its speed) the less kinetic energy the object will have
To increase the amount of gravitational potential energy in a system simply increase the height of the object in the system.
If I want to get more energy output, then increase the speed of the input. The more energy you put into the system, the more energy will come out of the system.
When using a fidget spinner generator, the magnets used in the generator system when spinning over the coper coil transform the kinetic energy into electrical energy which lights the bulb.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
