What is the strongest force on Earth?

Back

Gravity is the strongest force on Earth.

Front

Friction and air resistance always exert force...

Back

in the opposite direction of the object's motion.

Front

What is the missing force in the context of forces?

Back

Frictional force is a type of force that opposes motion.

Front

What type of force is exerted between two people through a rope?

Back

Contact Pull is the force exerted when two objects are in direct contact.

Front

How can friction be reduced?

Back

Friction can be reduced by reducing the force acting between the surfaces, reducing the roughness of the surfaces, or using lubricants like wax, grease, or oil.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What are the two main types of friction?

Back

The two main types of friction are static friction and kinetic friction.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of an object that is already moving.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts on objects as they move through the air.
