What is acceleration?

What is a force?

Select the box that will accelerate.

Which force is represented by the arrow?

What is the upward force acting on the plane?

What is the forward force (represented by the arrow pointing left) acting on this plane?

What causes the force of drag?

Assuming both person A and person B have the same amount of air resistance, which person is accelerating towards the ground faster?

The force of air resistance increases as falling speed increases. Terminal velocity is reached when the air resistance force balances the gravitational force. What is your acceleration rate when you reach terminal velocity?

Your parachute opens and you slow down a lot! Which force diagram best represents the forces acting on you when you open your parachute?

The air resistance force decreases as you slow down and you once again reach terminal velocity.

Which force diagram best shows terminal velocity with a parachute?

You have safely landed!

Gravity is still pulling you towards Earth.

What upward force is now acting on you, as shown in the diagram?

According to Newton's Third Law, what is happening as your feet apply a force to the ground?

You run an average speed of 200 meters/min for 20 minutes until you reach Balanced Rock. How far do you travel in this time?

Next, you run 9300 meters in 40 minutes to Delicate Arch. What is your average speed during this time?

(Round your answer to the nearest whole number.)

About how many meters did you run after 60 minutes?

Which part of the graph represents the 10 minute break you took at Balanced Rock?

What is your average speed for the entire 70 minutes?

According to Newton's First Law, why is it harder to GET your bike going that it is to KEEP your bike going?

What would inertia do to you if your bike hits a big rock?

Why is it harder to ride with a heavy backpack on?

Moving at the same initial speed in both cases, is easier to stop with or without the heavy backpack on?

Your bicycle tires pushing against the Earth is the _________ force while the Earth pushing on the tires equally is the _________ force.
