Terms in this set (20)
scalar quantity
a quantity that can be described by magnitude only and has no direction
vector quantity
a quantity that has both magnitude and direction
average velocity
the total displacement divided by the time interval during which the displacement occurred
Uniform Motion
-motion with a constant velocity
object is at rest
position- time graph
object is at constant velocity
position time graph
object is accelerating
position time graph
Instantaneous Velocity
-velocity of an object at a specific instant in time
-on a curve it is found at a tangent on a d-t graph
-object is moving at constant speed
velocity time graph
-constant acceleration
Velocity time graph
Negative Acceleration
Slowing down in positive direction
Speeding up in negative direction
Positive Acceleration
Speeding up in positive direction
Slowing down in negative direction
Slope of Velocity vs. Time graph
This equals acceleration
Slope of Position vs. Time graph
This equals velocity
Area of Velocity vs. Time graph
This equals change in displacement
Vertical motion of a projectile
1. Force = Weight (the pull of gravity acting on the object)
2. Acceleration = -9.81 m/s/s
3. Velocity changes 9.81 m/s per second
Horizontal motion of a projectile
1. Force = none
2. Acceleration = none
3. Velocity is constant due to inertia
A key idea of projectile motion
Horizontal and vertical components of a projectile have NOTHING to do with each other. (They are almost independent of one another.)
Maximum height of projectile motion
The point where the vertical velocity is the lowest (0)
Minimum height of a projectile
The point where the vertical velocity is the greatest
