Kinematics

I fertilize 5 plants in a 10 plant outdoor garden to see if the fertilizer will improve plant growth. What's the dependent variable?

• Fertilizer

• Water

• Plant Height

• Sunlight

I fertilize 5 plants in a 10 plant outdoor garden to see if the fertilizer will improve plant growth. What's the independent variable?

• Fertilizer

• Water

• Plant Height

• Sunlight

Soil type, sunlight, water, and temperature should all be kept the same for all 10 plants. These are examples of

• Independent Variables

• Dependent Variables

• Controlled Variables

• Groups

An increasing slope, like graph C means that the object is

• Moving away from start

• increasing speed

• accelerating

• all of the above

Which graph shows a person jogging away at a constant pace?

• A

• B

• C

Your velocity and speed are the same number. (ex. 60 miles per hour). But speed...

• Includes direction

• Does not include direction

Susan drives 60 miles per hour on the highway for 2 hours. How far did she go?

• 25 miles

• 50 miles

• 75 miles

• 120 miles

Which one is NOT an example of acceleration?

• Speeding up

• Slowing Down

• Turning

• Jogging at a steady speed

A person already walking at 1 m/s takes 2 seconds to reach a top speed of 5 m/s. What is their acceleration?

• 1 m/s^2

• 2 m/s^2

• 4 m/s^2

• 10 m/s^2
