Non Contact Forces

Front

What is a non-contact force?

Back

A force that acts on an object without physical contact, such as gravity, magnetism, and electricity.

Front

What is gravity?

Back

The force of attraction between all things with mass.

Front

What is electricity?

Back

Energy as an accumulation of charge or dynamically as a current.

Front

What is magnetism?

Back

A force that can attract or repel certain materials, typically associated with magnets and electric currents.

Front

What is friction?

Back

The resistance that one surface or object encounters when moving over another.

Front

Give an example of a non-contact force.

Back

Gravity, electricity, and magnetism are all examples of non-contact forces.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects towards the center of the Earth, giving them weight.

Front

What role does electricity play in non-contact forces?

Back

Electricity can create electric fields that exert forces on charged objects without direct contact.

Front

What is the relationship between magnetism and electricity?

Back

Electric currents can produce magnetic fields, and changing magnetic fields can induce electric currents.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical interaction between objects, while non-contact forces act at a distance.
