Front

What is the formula for density?

Back

density = mass / volume

Front

How do you convert minutes into seconds?

Back

Multiply by 60

Front

Why do objects sink or float in water?

Back

Because their densities are higher or lower than compared to water

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Speed - Initial Speed) / Time

Front

What is the unit of density in the metric system?

Back

Kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³)

Front

What is the relationship between mass, volume, and density?

Back

Density is mass divided by volume.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

The density increases.

Front

What is the effect of temperature on the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases.

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = length × width × height
