What is measured in m/s?

Speed, Velocity

What is measured in m/s^2?

Acceleration

What can be measured in meters (m)?

Distance, Displacement

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

Displacement symbol-

Delta X (triangle X)

Displacement unit-

meters (m)

Distance unit-

meters (m)

Scalar-

Does not include direction, only size

Vectors-

Include direction and magnitude (how much)

Average speed=

Distance/Time

Average velocity=

Displacement/Time

What is Average speed and Average Veloctiy measured in?

m/s

Average=

How fast you are going on Average

Instanteous=

How fast you are going in the moment

In a postion v. time graph, what does the slope tell you?

Average Velocity

What does the rise/run = in a p v. t graph?

Delta X/T (Displacement/Time in Secs)

What is the postion symbol?

X

What is position measured in?

meters (m)

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?

m/s^2

What is the acceleration of falling objects on earth?

-10 m/s^2

Name the vectors-

Displacement, Velocity, Acceleration

Name the Scalars-

Acceleration

What does the y-intercept represent in a v v. t graph?

Starting velocity

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?

Speeding Up

When the signs of velocity and accleration are different, is the object speeding up or slowing down?

Slowing Down
