Phy-Laws of Motion

N's Laws of Motion

QuestionAnswer
A push or pull exerted on an object force
A force that resists motion in two objects that are moving against each other friction
The unit of force that equals 1kg x m/sec^2 Newton
velocity/time; The rate of change in velocity over time. acceleration
The total of all forces acting on an object net force
The tendency of an object to resist a change in its movement inertia
The change in velocity of an object traveling in a circular path centripetal acceleration
The property of a moving object that depends on its mass and velocity momentum
A point against which the position of an object is measured reference point
The constant velocity after which an object stops accelerating terminal velocity
The result of unbalanced forces in a system where the net force is not 0; It occurs when an object changes position in relation to a reference point. motion
The law of inertia. The greater the mass, the greater the inertia. Newton's 1st Law of Motion
The force applied = the object's mass times the acceleration; F=ma Newton's 2nd Law of Motion
For every action, there is an equal and opposite reaction. Newton's 3rd Law of Motion
The speed of an object in a particular direction velocity
distance / time; The rate at which an object moves. speed
The force of attraction acting between all matter gravity
It determines the ways in which electrically charged particles interact with each other and with magnetic fields electromagnetic force
It holds the protons and neutrons in the nucleus of the atom and overcomes the repulsion between the protons strong nuclear force
The force in an atomic nucleus responsible for radioactivity, and prompts the nuclear fusion reaction that fuels the sun. weak nuclear 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.
