Gravity
Name one of the two things that will affect how fast an object falls to the ground.
What is shape or weight?
Objects with the same charge do this to each other.
What is repel?
Magnetic force is strongest at these parts of a magnet.
What are the poles?
Was it easier to attract or repel the car with the magnet?
What is repel?
Pushing or pulling an object is an example of this type of force.
What is a contact force?
I discovered gravity when an apple fell on my head.
Who is Isaac Newton?
Objects with opposite charges do this to each other.
What is attract?
A compass is actually one of these.
What is a magnet?
The Earth is a giant magnet because its core is made from these two materials.
What are iron and nickel?
Throwing a basketball into a net is an example of this kind of contact force.
What is a push?
Objects like a parachute create this which slows their fall to the Earth.
What is air/wind resistance?
When an atom has more of these than protons it is negatively charged.
What are electrons?
These three materials are the most common magnetic materials.
What are iron, nickel and cobalt?
This pole points north on a compass.
What is the south pole?
All non-contact forces are this.
What is invisible?
This is much weaker on the moon than it is on Earth.
What is gravitational pull or gravitational force?
When you shake hands with a friend and get a zap it is because of this.
What is static electricity?
During the experiment, this material reduced the magnets strength the most.
What is metal?
All magnets are surrounded by this thing you cannot see.
What is a magnetic field?
Climbing a rope is an example of this contact force.
What is a pull force?
I am the measurement of gravity pulling you towards the Earth.
What is weight?
When we feel a shock negative electric charges are doing this to positively charged objects.
What is jumping?
These are the two ways to create a temporary magnet.
What are rubbing or striking?
When you rub a piece of metal with a magnet you are lining up all of these in the same direction, creating a temporary magnet.
What are atoms?
The brakes on your car slow you down because of this kind of contact force.
What is friction?
