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 do you calculate Net Force?

Back

Net Force is calculated by adding all the forces acting in one direction and subtracting the forces acting in the opposite direction.

Front

What is density?

Back

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

Front

Which is denser: water or cooking oil?

Back

Water is denser than cooking oil.

Front

What happens to the kinetic energy of water molecules when water freezes?

Back

The kinetic energy of water molecules decreases, causing them to move slower and fix into place.

Front

What type of energy do plants convert during photosynthesis?

Back

Plants convert radiant energy (light energy) into chemical energy (food).

Front

What is the relationship between mass and density?

Back

Density is directly related to mass; as mass increases, density increases if the volume remains constant.

Front

What is the principle of buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, determined by the object's density compared to the fluid's density.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = Mass x Acceleration (F = m*a).

Front

What happens to the volume of water when it freezes?

Back

The volume of water increases when it freezes, causing ice to float.
