Topic 2: Force and Motion

velocity

• speed in a specific direction

• the rate of change of position

• the distance traveled over time

• the speed of an object regardless of direction

force

• A push or a pull

• A type of energy

• A measure of mass

• A unit of speed

slope

• Steepness of a graph at a given point

• The angle of elevation from the horizontal

• The rate of change of a function

• The distance between two points on a graph

displacement

• length of a straight line between two points

• the total distance traveled regardless of direction

• the distance between two points along a curved path

• the change in position of an object over time

uniform motion

• motion of an object with a velocity that does not change

• motion of an object that speeds up or slows down

• motion of an object that changes direction constantly

• motion of an object that is at rest

speed

• ratio of distance traveled to the amount of time taken

• the distance covered in a straight line

• the total time taken for a journey

• the average velocity of an object

inertia

• Tendency of an object to remain stationary or to remain in motion

• Force that causes an object to accelerate

• Resistance of an object to change its state of motion

• Energy possessed by an object due to its motion

unbalanced force

• A force that is equal in magnitude and opposite in direction to another force

• A force on an object that is not canceled by other forces

• A force that acts on an object at rest

• A force that always results in a change of direction

distance

• total length of the path actually taken from Point A to Point B

• the shortest path between two points

• the difference in elevation between two points

• the speed at which an object travels from one point to another

magnitude

• Size or importance

• A type of measurement

• A mathematical operation

• A unit of distance
