EMS 6th Gr. Science

motion definitions

QuestionAnswer
speed equation distance divided by time
speed the rate at which an object moves
motion a change in postion in a certain amount of time
average speed speed that changes over time
constant speed speed that does not change over time
velocity speed in a given direction
acceleration rate of change in velocity
deceleration a decrease in velocity
momentum depends on the mass of the object and the velocity with which it is traveling
acceleration equation (final velocity-orginal velocity)divided by time
momentum mass x velocity
average speed final distance divided by final time
Types of Friction Rolling, Fluid, Sliding
Rolling Friction Produced by such objects such as wheels or ball bearings. Tends to be less than sliding friction.
Sliding Friction When solid objects slide over each other
Balanced Force force acting on an object that will NOT change the object's motion
Unbalanced Force force that acts on an object that will change its direction
Force A force gives energy to an object, sometimes causing it to start moving, stop mofing or change direction. A push or a pull
Friction A force that acts in a direction opposite to the motion of the moving object. Friction will cause a moving object to slow down or stop.
Fluid Friction Occurs when objects move accross or through fluids or gases
Sir Isaac Newton Laws of motion
1st law Inertia - an object a rest remains at rest and an object in motion remains in motion unless acted upon by an unbalanced force.
2nd Law Force = mass x acceleration (the larger the force the larger the acceleration)
3rd Law Every action has an equal and opposite reaction.

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.
