What is measured in m/s?
What is measured in m/s^2?
What can be measured in meters (m)?
What is distance?
How far you have traveled. How many steps you have gone. Direction not needed. (fitness)
What is displacement?
How far you are from your starting point. Include direction
Delta X (triangle X)
Does not include direction, only size
Include direction and magnitude (how much)
What is Average speed and Average Veloctiy measured in?
How fast you are going on Average
How fast you are going in the moment
In a postion v. time graph, what does the slope tell you?
What does the rise/run = in a p v. t graph?
Delta X/T (Displacement/Time in Secs)
What is the postion symbol?
What is position measured in?
What does it mean when the slope is zero?
Horizontal Line, Stopped
What is acceleration?
Change in velocity over time
3 ways to accelerate?
1. Change in direction
2. Speed up (start moving)
3. Slow down (stop moving)
How can a falling object speed up?
By falling for longer
How do you slow down an object in motion?
Push in opposite direction of motion
How do you make a moving object go faster?
Push in direction on current motion
What is acceleration measured in?
What is the acceleration of falling objects on earth?
Name the vectors-
Displacement, Velocity, Acceleration
Name the Scalars-
What does the slope represent in a p v. t graph?
What does the sign of the slope mean in a p v. t graph?
What does the y-intercept of a p v. t graph represent?
What does the steepness of a slope mean in a p v. t graph?
What does the slope represent in a velocity v. time graph?
What does the y-intercept represent in a v v. t graph?
When is the velocity of a object thrown upward zero?
At the highest point
When the sign of velocity = + and the sign of accleration = +, is it speeding up or slowing down?
When the signs of velocity and accleration are different, is the object speeding up or slowing down?
Sign for average velocity
What is average velocity measured in?
Initial Velocity Sign
Initial velocity unit
Final Velocity Sign
Final Velocity unit?
