Physics Unit Test

You can increase acceleration by increasing this. Force
What does Newton's 2nd Law state? The acceleration of an object depends on the object's mass and the net force acting on it.
What are the two formulas for acceleratiion? net force / mass and (final velocity - initial velocity) / change in time
What is the formula for force? mass * acceleration
What are the units for force? Newtons and kg * m/s^2
What does Newtown's 3rd law state? For every action, there is an equal and opposite reaction.
What is the formula for momentum? mass * velocity
What is the unit for momentum? kg * m/s
Movement results from this type of force: unbalanced
What is terminal velocity? When an object reaches its greatest velocity while falling. When the force of air resistance = the weight of the object.
Formula for speed: Distance / time
Formula for distance: speed * time
Formula for time: distance / speed
Three ways an object can accelerate: speed up, slow down, change direction
What is a balanced force? Opposing equal forces that cancel each other out.
What are the two ways to increase the acceleration of an object? Increase force or decrease mass.
Why would an object have more inertia? (Newtown's 1st Law) Because it has more mass, and the more mass an object has, the more inertia it has, and the harder it is to start and stop.

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.
