Safety review

Physical Science Safety

TermDefinition
momentum vector quantity which is a product of mass and the velocity of an object
conservation of momentum total momentum before equals the total momentum after a collision
inertia a mass resistance to change --more mass more inertia
Newton's 1st Law object keeps doing what it is doing unless an outside force works on it
Newton's 2nd Law The direction of the acceleration of a mass is in the direction of the unbalanced force
Kinetic Energy the energy an object has because they are in motion depends on mass and velocity of the object
Work force times distance equal to change in energy
force diagram diagram that shows all forces acting on an object
Balanced force All force add to zero--object will continue to do what it is doing
Whiplash neck injury to the muscles of the neck
inelastic collisions when two objects collide and stick or stick together and have one velocity
elastic collisions when two objects collide and "bounce " off each other
Crumple zone part of a car that helps extend the time of change in momentum in a collision therefore decreasing the force felt in the car.
Impulse time for the change of momentum to happen
Force push or pull
Net force the sum of all forces working on an object
unbalanced force objects will accelerate in the direction of the unbalanced force
acceleration change in velocity per unit time
vector has both magnitude and direction

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.
