Forces and Friction

Front

What is the force of gravity acting on an object called?

Back

Weight

Front

Define force.

Back

A force is a push or a pull upon an object resulting from the object's interaction with another object.

Front

What happens to the gravitational force as mass increases?

Back

It increases.

Front

What is friction?

Back

Friction is a resistance force.

Front

What two factors affect the magnitude of the force of gravity between two objects?

Back

Mass and Distance.

Front

What is the formula for calculating weight?

Back

Weight = Mass × Gravitational Acceleration (W = m × g).

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is static friction?

Back

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

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

How does surface texture affect friction?

Back

Rough surfaces generally have higher friction than smooth surfaces.
