displacement - correct answers ✅distance and direction of an object's change in position from the starting point distance - correct answers ✅how far an object moves balanced forces - correct answers ✅forces that are equal in size and opposite in direction; they do not move an object and the net force is equal to zero. average speed - correct answers ✅total distance divided by total time instantaneous speed - correct answers ✅speed at a given point in time unbalanced forces - correct answers ✅forces that are unequal in size and the direction is the same; they cause an object to move velocity - definition - correct answers ✅the speed and direction of an object's motion (m/s) velocity - symbol - correct answers ✅v
acceleration - definition - correct answers ✅The rate at which an object's velocity increases or decreases (m/s^2) acceleration - symbol - correct answers ✅a time - definition - correct answers ✅The duration of an event (i.e. The ball was in the air for 4 seconds) time - symbol - correct answers ✅t seconds - definition - correct answers ✅A unit of time seconds - symbol - correct answers ✅s force - definition - correct answers ✅A push or a pull on an object force - symbol - correct answers ✅F Newton - definition - correct answers ✅unit for force Newton - symbol - correct answers ✅N
Newton's 1st Law of Motion - correct answers ✅an object in motion stays in motion and an object at rest stays at rest until a net force acts upon the object Newton's 2nd Law of Motion - correct answers ✅Force= mass x acceleration; the larger something is, the harder it is to move Newton's 3rd Law of Motion - correct answers ✅Forces always occur in pairs; the forces will always be equal and opposite friction - correct answers ✅a force that OPPOSES motion between two surfaces that are touching each other; it slows down the motion of objects static friction - correct answers ✅friction between two surfaces that are not moving past each other sliding friction - correct answers ✅friction that opposes motion between two surfaces sliding past one another rolling friction - correct answers ✅friction between a rolling object and surface it rolls on
Law of Gravitation - correct answers ✅the law that states that the force of gravity depends on the mass and distance between the objects Mass - correct answers ✅the amount of matter in an object; stays the same no matter where you are Weight - correct answers ✅the force of gravity pulling on a body; changes as gravitational force changes acceleration of gravity on Earth - correct answers ✅-9. m/s^ work - correct answers ✅the transfer of energy that occurs when a force makes an object move in the direction of the applied force; measured in joules (lifting weights, moving a desk) resistance - definition - correct answers ✅an electrical device that resists the flow of electrical current; measured in Ohms resistance - unit - correct answers ✅Ohms
Equilibrium - correct answers ✅when the net force on an object is zero Potential energy - correct answers ✅The energy that an object has the potential of putting out (i.e. an object higher in the air will have more potential energy because it has more space to accelerate) (mgh) Kinetic energy - correct answers ✅The energy an object is using in motion (i.e. a moving car has kinetic energy) ((1/2)mv²) Change in x for two dimentional motion - correct answers ✅x=x.+v.t+(.5at²) Net Force equation - correct answers ✅mass * acceleration displacement equation - correct answers ✅d=xf-xi Power equation - correct answers ✅IV Work equation - correct answers ✅force × distance
Vf= - correct answers ✅Voy + at change in X= - correct answers ✅(change in V) x t change in Y= - correct answers ✅Vot + 1/2at^ Vf^2= - correct answers ✅Vo^2 + 2ax
