What is a non-contact force?

Back

A non-contact force is a force that can act on an object without physical contact, such as gravitational force, magnetic force, or electric force.

Front

Give an example of a non-contact force.

Back

Examples of non-contact forces include gravity, magnetism, and electrostatic forces.

Front

What is a contact force?

Back

A contact force is a force that occurs when two objects are in physical contact with each other.

Front

Provide an example of a contact force.

Back

Examples of contact forces include friction, tension, and normal force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object, which pulls the object towards the center of the Earth.

Front

What role does friction play in contact forces?

Back

Friction is a contact force that opposes the motion of an object sliding or rolling over a surface.

Front

What is tension in the context of contact forces?

Back

Tension is the pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

How do magnetic forces act as non-contact forces?

Back

Magnetic forces can attract or repel objects without direct contact, such as magnets affecting each other or magnetic materials.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion, while unbalanced forces result in a change in motion.

Front

What is the principle of action at a distance?

Back

The principle of action at a distance states that an object can exert a force on another object without being in physical contact.
