What is a load?

__________ is the force that pulls you toward Earth
What is gravity?
Name an object that would be attracted to a magnet
Give me an example of a force
Pushing a grocery cart, dragging a luggage, playing on a see saw etc
What is a landslide?

Give me an example of muscular force
kicking a ball, a push up, etc
Give me an example of low friction (not a lot of friction)
socks on tile, oil on tile (something slippery)
List 3 natural forces talked about in our unit:
Gravity, Electrostatic, Friction, Soil Erosion, Landslides,
_____________ is the force that acts on objects that rub against each other.
People can float out in outer space because there is very little
gravity
What would fall to the earth quicker? A Stick or a leaf? Explain why.
A Stick because it has a higher mass.
Name some ways you can stay SAFE from forces
Seatbelt can keep you safe if your car gets into an accident, safety helmet keeps your head safe, knee pads when you're playing sports
__________ is the push or pull force that happens with charged objects.
What is electrostatic?
Lightning is an example of
electrostatic force
True or false? All magnets have two opposite poles: north and south. In order for magnets to stick to one another, north must be with north and south must be with south.
FALSE. They will repel each other. Opposites must be together (north and south)
Soil erosion is the washing or blowing away of the top layer of soil. Why can this be dangerous?
It pollutes rivers, lakes, and water systems. Farmers can't grow crops on eroded soil.
_________ is the force is applied using parts of the body like arms or legs.
What is muscular?
Give me an example of high friction (lots of rubbing)
Car tires on a road...
