1-D Forces

1-D Forces, Newton's Laws

TermDefinition
Inertia An object's ability to resist change in its state of motion
Force A push or pull or another outside affect that acts on an object. Equation- F=ma Unit - kgm/s/s = Newtons, N
Friction A non-conservative force that acts in the opposite direction of the objects motion. Friction always reduces Net Force.
Momentum An object's ability to resist change in motion. Object's have momentum only when they are moving.
Mass How much matter an object contains. *The total number of atoms an object has. This does not change based upon location.
Weight An object's force due to gravity. The object's mass x gravity. This changes depending upon the location of an object.
Gravity A form of acceleration based upon the MASS of an object. Acceleration due to gravity on Earth = -9.8m/s/s.
Newton's 1st Law **Known as the Law of INERTIA** An object will maintain its state of motion unless an outside net force acts on the object.
Newton's 2nd Law **Known as the Law of PROPORTIONS** An object's acceleration is directly proportional to the force acting on the object and inversely proportional to the mass of the object. As MASS inc. ACCELERATION decr. As FORCE inc. ACCELERATION inc.
Newton's 3rd Law **Known as the ACTION/REACTION** For every force there is another force equal in magnitude and opposite in direction. **ONE OBJECT MAY NOT EXERT ANY MORE FORCE THAN ANOTHER OBJECT CAN WITHSTAND**
Static Equilibrium Net Forces on an object are = 0, zero Newtons AND the object is at rest.
Dynamic Equilibrium Net Force on an object are = 0, zero Newtons AND the object is in motion. **Think cruise control**
Collisions When two or more objects interact with one another exerting equal forces upon one another.
Net Forces The addition of all forces acting on an object. Generally done in one dimension. Equation: ∑F= F1 + F2 + Fn Unit: N, Newtons
Conservation of Momentum and Energy Interactions with objects will result in momentum and energy being conserved within a system. Energy and momentum may be lost by individual objects but the conservation can be tracked within the system.
Free Fall An object moving in the Y-Axis falls without any opposing force as it falls. NO FRICTION.
Free Body Diagrams An image that outlines and describes all the forces acting on a system. Fn= Force Normal/support force (Always up) W = weight (Always down) m*g Fg= Force due to gravity Ff= Force of friction Fdrag = Force of air resistance Fa = Force applied

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.
