Science Force/Motion

Science Force/Motion Test

QuestionAnswer
A change in position is motion
The measure of the pull of gravity on an object is an object's weight
The ability to do work Energy
The energy of motion Kinetic Energy
A force that pulls all objects toward each other (and us to the ground) is gravity
_____ is how fast an object moves from one position to another speed
The measure of a force moving an object is work
A push or pull is a force
Energy that is stored not used Potential Energy
Energy of moving parts Mechanical Energy
The tendency of an object to resist change in its motion Inertia
F = m.a Newton's 2nd Law
For every force there is an equal and opposite force Newton's 3rd Law
the rate of change in Velocity Acceleration
Speed in a specific direction Velocity
True or false: Pushing on a wall is NOT work. True
True or false: Riding a bike is an example of work. True
True or False: 23 meters per second (m/s) is a measure of acceleration. False
True or false: 70 miles per hour is a measure of SPEED. True
Tool used to measure Forces such as weight Spring scale or Forcemeter
Do not change an object's motion Balanced Forces
Cause a change in motion Unbalanced Forces
Newton's 2nd law of motion states that F= m.a So objects with more mass have Less acceleration
Newton's 2nd law of motion states that F= m.a So objects with less mass have More acceleration
Newton's 1st law of motion states that an object at rest wants to stay at rest as long as the forces acting on it are Balanced Forces
Newton's 1st law of motion states that an object in motion wants to stay in motion unless Unbalanced forces act on it
For every action there is an equal and opposite reaction Newton's 3rd law of motion
For every force there is an equal and opposite force

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.
