What is the effect of a positive slope on a position vs. time graph?
The object is moving in the positive direction.
What is the effect of a negative slope on a velocity vs. time graph?
The object is slowing down (decelerating).
What is the effect of gravity on an object thrown upwards near Earth's surface?
The object experiences a constant downward acceleration of approximately 10 m/s².
What happens to the maximum height of a projectile if gravity is halved?
The maximum height doubles.
What is the effect of constant acceleration on an object's velocity?
The object's velocity changes uniformly over time.
What is the effect of gravity on an object near Earth's surface?
It causes a constant downward acceleration of approximately .
What is the effect of a constant positive acceleration on an object's velocity?
The object's velocity increases linearly with time in the positive direction.
What is the effect of a constant negative acceleration on an object's velocity?
The object's velocity decreases linearly with time, or increases in the negative direction.
What is the effect of a non-zero slope on a position vs. time graph?
It indicates that the object has a non-zero velocity.
What is the effect of a non-zero area under a velocity vs. time graph?
It indicates that the object has a non-zero displacement.
How do you find instantaneous velocity from a position vs. time graph?
Determine the slope of the tangent line at the point of interest on the position vs. time graph.
How do you find displacement from a velocity vs. time graph?
Calculate the area under the curve between the initial and final times on the velocity vs. time graph.
How do you find the change in velocity from an acceleration vs. time graph?
Calculate the area under the curve between the initial and final times on the acceleration vs. time graph.
How do you solve for final velocity with constant acceleration, given initial velocity and time?
Use the equation: .
How do you solve for final position with constant acceleration, given initial position, initial velocity, and time?
Use the equation: .
