Forces and Magnetism Concepts

Front

What is the Law of Gravity?

Back

The Law of Gravity states that every object in the universe attracts every other object with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.

What happens when you jump into the air?

Back

When you jump into the air, you are applying a force that temporarily overcomes the force of gravity, allowing you to rise.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, slowing it down.

Front

Why does a parachute slow down a falling person?

Back

A parachute creates air resistance, which counteracts the force of gravity and slows the fall.

Front

What happens when two north poles of magnets are brought together?

Back

The two north poles repel each other.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

Which surface creates the most friction for a toy car?

Back

A sandy beach creates the most friction for a toy car.

Front

What materials are typically attracted to magnets?

Back

Materials like iron, nickel, and cobalt are typically attracted to magnets.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be detected.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow through it easily, while an insulator resists the flow of electricity.
