Exploring Different Types of Forces

What is a contact force?

• A contact force is a force that acts at a distance without physical contact.

• A contact force is a type of energy that can be stored in objects.

• A contact force is a force that only acts on stationary objects.

• A contact force is a force that acts between two objects that are in direct physical contact.

Can you name a type of magnetic force?

• Magnetic repulsion

• Magnetic attraction

• Electromagnetic radiation

• Static electricity

What pulls objects towards the Earth?

• Friction

• Gravity

• Air pressure

• Magnetism

What force is created by charged particles?

• Nuclear force

• Frictional force

• Gravitational force

• Electromagnetic force

What is friction?

• Friction is the force that enhances the relative motion of two surfaces in contact.

• Friction is the energy produced when two surfaces are heated together.

• Friction is the force that opposes the relative motion of two surfaces in contact.

• Friction is the speed at which two surfaces move past each other.

What do we call a force we apply to move something?

• Weight

• Force

• Energy

• Momentum

Is gravity a contact force or a distance force?

• Gravity is a distance force.

• Gravity is a contact force.

• Gravity only affects large objects.

• Gravity is a magnetic force.

What happens when two magnets attract each other?

• The magnets float away from each other when they attract.

• The magnets repel each other due to their similar poles.

• The magnets pull towards each other due to their opposite poles attracting.

• The magnets create a loud noise when they attract.

Can you give an example of a frictional force?

• The normal force acting on a standing person.

• The tension in a rope during a tug-of-war.

• The force of gravity acting on a falling object.

• The frictional force between a book and a table when the book is pushed.

What force keeps us on the ground?

• Gravity

• Friction

• Air resistance

• Magnetism
