Distance and Displacement
This is needed to describe motion accurately and completely
What is a frame of reference
This is the speed an object has a a specific instant
What is instantaneous speed
This is the acceleration due to gravity
What is 9.8 m/s2
This is defined as a push or a pull
What is a Force
This is the tendency of an object to resist changes in motion
What is inertia
This is movement in relation to a frame of reference
What is relative motion
This is represented by the slope of a line on a distance time graph
What is speed
Objects may be accelerating while moving at a constant speed if this is happening
What is it is changing direction
This is the overall force acting on an object after all the forces are combined
What is Net Force
This Law states that the acceleration of an object is equal to the net force acting on it divided by the objects mass.
What is Newton's Second Law of Motion
This is the length between two points
What is distance
Two or more vectors can be added together using this method
What is vector addition
This is the constant change in velocity of an object
What is constant acceleration
This is the strongest of the four frictional forces
What is static friction
This is the force of gravity acting on an object.
What is weight
This is the length in a straight line from the starting point to the ending point of an objects motion
Vectors should be subtracted from each other if this is the case
What is they are in opposite direction from one another
The slope of a line on a speed-time graph is always this
What is linear
These are the four frictional forces
This is a measure of an objects inertia.
What is mass
This is the sum of two or more vectors
What is a resultant vector
This is an instrument that was once used as an essential aid to sea navigation
What is a sextant
This is how fast an objects velocity is changing at a specific instant
What is instantaneous accelerstion
The combination of initial forward velocity and the downward vertical force of gravity causes causes the ball to follow a curved path in this type of motion
What is projectile motion
This is the product of an objects mass and its velocity
What is Momentum.
