Newton's 3 Laws

TermDefinition
Force Push or pull one object exerts on another.
What is F and how is it measured? Force and Newtons (N)
Net Force The combining of forces when two or more forces act on an object.
Balanced Forces Forces that are equal in size and opposite in direction.
Unbalanced Forces Forces that are not equal in size and opposite in direction.
Founder of the 3 Laws of Motion Sir Isaac Newton
Newton’s 1st Law An object will move at a constant velocity until a net force acts on it.
Newton’s 1st Law is also known as Law of Inertia
Inertia The tendency of an object to resist a change in motion.
Friction resistance to motion when two objects are in contact with one another
Air resistance resistance an object feels when travelling through the air
Gravity the attraction two objects have on one another
Static Friction force between two surfaces that are NOT moving past each other
Sliding Friction force between two surfaces that are sliding past each other
Rolling Friction force between a rolling object and the surface it rolls on
Law of Universal Gravitation Depends of mass and distance
Gravity This force causes all falling objects to have an acceleration due to gravity of 9.8 m/s2.
Newton’s 2nd Law A net force acting on an object causes the object to accelerate in the direction of the net force.
Equation for Newton's 2nd Law F=ma
Mass is measured in _ kg
Acceleration is measured in _ m/s^2
Weight The force of gravity on an object
Mass the amount of matter in an object
Newton’s 3rd Law every action has an equal and opposite reaction
Momentum mass in motion
Momentum's symbol is _ p
Momentum is measured in _ Measured in kg*m/s
Equation of momentum p = mv
Velocity is measured in _ m/s
Law of Conservation of Momentum momentum is never created or destroyed in a collision, it only is transferred

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.
