Types of Forces
List 3 things that magnets will stick to
The whiteboard, paper clips, metal on a clipboard, some fridges, another magnet
How can you change the shape of a rock?
You can throw it to break it
What are 2 safety features cars have?
Seat belts and air bags
What is an example of a natural force?
Wind, hurricane, tornado, earthquake, land slide, soil erosion
Which type of force brings something closer to you? (push or pull)
What is an example of high friction (rough)?
Rubber tires on the road, running on the sidewalk
How can you change the direction of a ball that was thrown towards you?
You can hit it with a baseball bat, you can catch it and throw it in another direction, you can kick it
What are safety features that roller coasters have?
seat belts, head rests, safety bars
Why is soil erosion bad for the environment?
It causes pollution in rivers and oceans, farmers cannot grow their crops without soil
What does it mean when magnets "attract" and "repel"?
Attract means that the magnet sticks to something and repel means that they do not stick or attach.
What is an example of low (slippery) friction?
Wearing socks on tiles, going down a slide, walking on ice
How can you make something go faster?
Kick it with a lot of force, push it down a slide, make less friction (add water to make a slide slippery)
Why should you wear a seat belt in a car?
Because it keeps you safe in your seat, especially in case of an accident.
What is a landslide?
A landslide is a natural force. It happens when rock and mud fall down from a steep slope. A landslide can harm people and damage homes.
What are 3 ways you used forces today?
Pull open a door, pull your dogs leash when going on a walk, push in your chair, pull a book off a shelf, used a magnet to stick something to the fridge
What is an example of static electricity?
Static in laundry, lighting, rubbing a balloon on your head
How can you stop a helium balloon from floating up?
Pull the string down, pop the balloon
Why do roller coasters have safety features?
Because they go very fast and sometimes upside down. You could fall out of your seat or hit your head.
What is soil erosion?
Soil erosion is when wind and rain (water) move the top layer of soil. The soil then pollutes rivers and makes it harder for farmers to use the land.
List 4 types of forces
What is the difference between contact and non-contact force? Give an example of each.
Contact force is when the two objects touch and non-contact force is when they do not touch. A contact force is when pushing open a door. A non-contact force is gravity.
How can forces make something go further apart?
When bowling, the ball hits the pins and spreads them out. When knocking over one domino, the rest fall over too.
What are 3 safety items you can wear to keep you safe when playing outside? (on a bike, playing sports, swimming)
How can humans prevent soil erosion?
Planting trees and plants, especially near rivers
Give an example of a muscular force, gravity and friction
Muscular: pushing a door open, pulling a balloon down
Gravity: a leaf falling from a tree, gravity keeps us on the ground
Friction: high friction would be a car on the road, low friction would be going down a water slide
