Forces, Densities, and Gravitational Attraction

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, depending on their masses and the distance between them.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is an example of a nonmetal?

Back

An example of a nonmetal is oxygen.

Front

What happens when two forces act in opposite directions?

Back

The resulting motion depends on the strength of the forces; the object will move in the direction of the stronger force.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in an object when it is stretched or compressed, like a rubber band.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational attraction.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its state of motion, causing it to accelerate, decelerate, or change direction.
