What is magnetic?
The force that attracts metals.
If two magnets try to connect their north poles what will happen?
They will repel.
Define "pull."
A force that brings an object closer.
Give me three examples of natural forces.
1. Gravity
2. Magnetic Force
3. Electrostatic Force
What is muscular?
The force that is applied using parts of the body like arms or legs.
A push up is an example of which force?
Muscular force
What would fall faster: a rock or a leaf? Why?
A rock because it is heavier (weight makes a difference!)
Define "push."
A force that moves an object away from something.
Give me three things that can protect you from the impact of forces.
1. Seatbelt
2. Helmet
3. Elbow/knee pads
The force that pulls objects toward the earth.
Rubbing two sticks together to create heat is an example of which force?
Friction
Because there is very little gravity
Define "load."
A weight or force that is acting on an object or body.
Give me three examples of non-contact force.
Using magnets to pull a paper clip
An apple falling from a tree
A pencil falling off a desk
What is electrostatic?
The push or pull force that happens with charged objects.
Lightning is an example of which force?
Electrostatic force
What is an example of low friction?
Wearing socks on a tile floor
Going down a plastic slide
What is a force?
A force is a push or a pull. A force can make an object start moving or stop moving.
Give me three objects that would be attracted to a magnet.
1. Iron nail
2. Steel pin
3. Nickel coin
What is friction?
The force that acts on objects that rub against each other.
What FORCES are involved in bowling?
Muscular force (pushing the ball down the lane)
Gravity (makes the pins fall down)
Friction (low friction - the ball on the lane)
What is an example of high friction?
Car tires on a road
Pulling on a rope
