Forces and Motion

QuestionAnswer
Acceleration is... the rate of change of velocity
Newton’s 2nd Law of Motion also referred to as the Law of Acceleration; the force of an object is equal to its mass multiplied by its acceleration
Isaac Newton an English scientist, mathematician, and astronomer credited with developing the 3 laws of motion
Newton’s 1st Law an object at rest will remain at rest unless acted upon by an unbalanced force
Newton’s 2nd Law the force of an object is equal to its mass multiplied by its acceleration
Newton’s 3rd Law for every action there is an equal and opposite reaction
Balanced Force equal forces which will not cause a change in an object’s motion
Net Force the overall (total) force acting on an object
Newton (N) the SI unit of force
Friction the resistance in motion when two surfaces are touching
Motion the process of changing place or position
Reference Point a stationary point that is used to determine the position of an object
Displacement the difference in position between the starting point and final point
Position location of an object compared to a reference point
Distance the amount of space between two points
Inertia an object’s tendency to resist a change in motion
Force a push or a pull on an object that may change the motion of the object
Speed the distance an object travels per unit of time
Velocity speed in a given direction
Constant Speed speed that remains the same or does not change
Average Speed the total distance traveled divided by the total time needed to travel that distance
Direction an object’s specific orientation in relation to a defined universal direction, such as north, south, east, or west
Magnitude the size, quantity, or intensity of an object, action, or event
Inverse Relationship When one value increases, the other value decreases

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.
