What is Net Force?

Back

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

What is an Element in chemistry?

Back

An Element is a pure substance that cannot be broken down into simpler substances. It is represented by a chemical symbol and consists of only one type of atom.

Front

What happens when forces are applied in opposite directions?

Back

When forces are applied in opposite directions, they can either cancel each other out or combine to create a net force, depending on their magnitudes.

Front

Which liquid is the least dense: oil, water, syrup, or plastic bottle?

Back

Oil is the least dense liquid among the options provided.

Front

What is a Normal Force?

Back

Normal Force is the support force exerted upon an object that is in contact with another stable object. It acts perpendicular to the surface.

Front

What is the formula for calculating Net Force?

Back

Net Force = Sum of all forces acting on an object.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

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 principle of buoyancy?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.

Front

What is friction?

Back

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