What is the basic unit for measuring length?

• Foot
• Meter
• Miles

What is speed?

• Distance an object moves in a given time
• Distance an object goes
• The time it takes to get somewhere

A turtle traveled 5 miles in 15 hours. What was its speed?

• 0.3 mph
• 3 mph
• 0 mph

In our experiment when we tested walking, skipping, and speed walking in the hallway, what was changing?

• Velocity
• Speed
• Distance

What is acceleration?

• Change in an object's speed in a direction
• Velocity after traveling a distance
• The speed before acceleration

What does it mean if acceleration is negative?

• The object is speeding up
• The object isn't moving
• The object is slowing down

What does Newton's First Law explain about objects that are not moving?

• They will start moving on their own
• They will stay at rest until something forces them to move
• They will always stop if you push them

According to Newton's Second Law, what happens if you try to push a heavy object?

• It's harder to move than a lighter object
• It's easier to move than a lighter object
• It will float in the air
