Forces and Their Types Flashcard

Front

What is the definition of Electrical Force?

Back

Electrical Force is the force responsible for the attraction or repulsion between charged particles.

Front

What is Normal Force?

Back

Normal Force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

Define Non-contact Force.

Back

Non-contact Force is a force that acts on an object without physical contact, such as gravitational, electrical, or magnetic forces.

Front

What is an Applied Force?

Back

Applied Force is a force that is applied to an object by a person or another object, resulting in a push or pull.

Front

What is Magnetic Force?

Back

Magnetic Force is the force exerted by a magnet on a magnetic material, such as iron, causing attraction or repulsion.

Front

What are the two main categories of forces?

Back

The two main categories of forces are contact forces and non-contact forces.

Front

Give an example of a contact force.

Back

An example of a contact force is friction, which opposes the motion of an object sliding over a surface.

Front

What is the role of friction in motion?

Back

Friction is a contact force that opposes the relative motion of two surfaces in contact, affecting the acceleration and speed of objects.

Front

Explain the concept of gravitational force.

Back

Gravitational Force is a non-contact force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, preventing it from starting to move, while kinetic friction acts on an object in motion, opposing its movement.
