Forces, Densities, and Gravitational Attraction

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds between atoms and molecules, which can be released during a chemical reaction.

What is a nonmetal?

Back

A nonmetal is a type of element that typically lacks the characteristics of metals, such as being a good conductor of heat and electricity. Nonmetals can be gases, liquids, or solids at room temperature.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

How does sound travel through air?

Back

Sound travels as a longitudinal wave through the air, moving via compression and rarefaction parallel to the direction of the wave.

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals. They are often semiconductors.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

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 kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be converted into kinetic energy.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Total applied forces - Total opposing forces.
