The force created through the use of your muscles.
Answers will vary.
What are the four ways you can change a force?
You can change its speed, direction, distance, and shape.
Provide 2 examples of natural forces or forces in nature.
Landslide, soil erosion, tornado, volcano, etc.
Seatbelt, knee pads, live vest, helmet, etc.
True or False: A force can make an object stop or start moving.
True
What is friction? Provide an example of friction.
Answers vary.
Provide an example of how you can change the shape of something by using force.
Ex. you can use muscular force to roll snow into the shape for a snowman.
Answer vary.

Gravity

The push or pull force that occurs with charged objects.
Answers vary.
Provide an example of how you can change the distance of something by using a force.
Ex. A rip current or undertow can pull you into the ocean and bring you further away from shore.
Answers Vary.
What three natural things cause a landslide?
Rain, floods, and earthquakes
What is the difference between high and low friction?
Bonus: can you provide an example of low friction?
High friction means you do not slip where low friction means the surface is more slippery. (low means go)
Bonus: socks on tile floor, wax on the floor at the bowling alley, sliding down a slide.
How does a force become balanced? (hint: push & pull)
When two forces are pushing against each other or pulling away from each other with the same strength.

Answer vary.
Provide an example of how a force can change the direction of something.
Answers Vary.
What is a tornado?
A column of air that spins very quickly.
What does it mean when forces are unbalanced?
It means there will be movement- one force is stronger than the other.
