Middle School Scienc

TermDefinition
Acceleration the rate at which an object changes its velocity
Applied Force force that is applied on an object by a person or another object
Balanced Forces equal and opposite forces on an object that result in no change in position, direction, or motion; combined net force equals zero
Force a push or pull that can change the position or motion of an object / material
Mass a measurement of the amount of matter in a sample
Net Force measurement of the total forces exerted on an object, measured in Newtons (N)
Newton's 1st Law the tendency of an object to resist change in motion unless acted upon by an outside net force
Newton's 2nd Law when an object that has a constant mass is acted upon by a force, the object will accelerate in the same direction as the net force
Newton's 3rd Law for every action, there is an equal and opposite reaction
Force pairs forces that occur in opposite directions and equal strengths at the point of contact between objects
Unbalanced force unequal forces acting on an object that may result in a change in position, direction, or motion
Amplitude measure of the size of the disturbance of a wave; height on the y-axis
Frequency the number of times a wave passes a certain point in a given amount of time
Wavelength the linear distance between identical points on successive waves
Normal Force Force perpendicular to the surface
Speed the distance an object moves per unit of time, such as miles per hour
Velocity speed in a direction
Distance Total of all changes in position.
Displacement The distance from the initial position to the final position and direction
Frictional Force Acts opposite the direction of motion. Contact force
Gravitational force The force that pulls straight down towards Earth. Noncontact force
Inverse relationship When something increases the other decreases
Direct relationship When something increases the other increases
Inertia Tendency to resist change in motion. Related to the mass of the object.

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.
