QuestionAnswer
How is speed defined? The distance an object travels divided by the time.
What is the formula for speed? s = d/t
What is constant speed? Speed that stays the same over time. This is very difficult to achieve.
What is velocity? Speed in a certain direction.
What is acceleration? The rate at which velocity changes.
What is free fall? Accelerated motion that happens when an object falls only with the force of gravity acting on it.
What is acceleration due to gravity? The value of 9.8 m/s2. This is the acceleration in free fall at the earth's surface.Often represented by the small letter g.
Force A push or pull.
Friction A force that resists the motion ob objects or surfaces.
Newton The metric unit of force, equal to the force needed to make a 1 kg object accelerate at 1 m/s2. 4.448 newtons=1 lbs.
Newton's 1st Law An object at rest will stay at rest and an object in motion will stay in motion with the same velocity unless acted on by an unbalanced force.
Newton's 2nd Law Acceleration is force divided by mass.
Newton's 3rd Law For every action force, there is a reaction force equal in strength and opposite in direction.
Potential Energy Energy of position.
Kinetic energy Energy of motion.

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.
