What is linearization?
Linearization is a technique to turn curved graphs into straight lines by manipulating the x-axis.
How do you determine velocity from a position vs. time graph?
Find the slope of the position-time graph.
How do you determine acceleration from a velocity vs. time graph?
Find the slope of the velocity-time graph.
How do you determine displacement from a velocity vs. time graph?
Find the area under the velocity-time curve.
How do you determine the change in velocity from an acceleration vs. time graph?
Find the area under the acceleration-time curve.
What is the effect of gravity on an object in free fall?
It causes the object to accelerate downwards at approximately .
What is the effect of applying a force at the center of mass of an object?
It causes linear acceleration without rotation.
What happens to the vertical velocity of a projectile at its maximum height?
The vertical velocity becomes zero.
What is the effect of increasing the angle of launch on the range of a projectile (assuming the same initial speed)?
The range increases until an angle of 45 degrees, then decreases.
What happens to the horizontal velocity of a projectile during its flight (ignoring air resistance)?
The horizontal velocity remains constant.
Define 'center of mass'.
The balance point of an object or system; the average location of all the mass.
Define 'free fall'.
When an object is only under the influence of gravity.
Define 'projectile motion'.
When an object is launched into the air and is only affected by gravity.
Define 'angled launches'.
Launches at an angle that include both a horizontal and vertical component of initial velocity.
Define 'vector components'.
The horizontal and vertical parts of a vector.
