Friction is a force that _________________ motion.

What is opposes?

When we go tubing in the winter, we use ________ friction?

What is sliding friction?

Definition of gravity
What is a force of attraction between objects?
100
A unit of force.
What is a newton?
200
The formula for average speed.
What is total distance traveled divided by the total time?
200

Describe the real cause of friction.

What are the unseen "hills and valleys" in an object's surface and the force acting on the object.

200

The type of friction when using a "dolley" to move a piece of furniture?

What is rolling friction?

200
Definition of weight
What is the measure of gravitational force acting on an object?
200

The hiker started at 2 m/s uphill, and took 10 minutes (600 s) to make it to the top but was only going 1 m/s at the top. Was the hiker accelerating?

Daily Double: (bet) IF there is an acceleration, how would you calculate it?

Yes - but acceleration is (-) negative.  Or deceleration.

v2 - v1 (1m/s - 2m-s) divided by the time it took (600 s).

300
This is the average speed when I travel 300 miles in 3 hours.
What is 100 miles per hour?
300
Friction does this to a moving object.
What is slow it down or stop it completely.
300

Two ways to increase friction

Push the surfaces together harder. Make one(or both) of the surfaces rougher.
