Physics Concepts Quiz

What is the measure of the amount of matter in an object known as?

• mass

• density

• volume

• weight

Which unit is commonly used to measure mass?

• liter

• gram

• pound

• kilogram

How can volume be defined?

• Volume is the quantity of three-dimensional space enclosed by a closed surface.

• Volume is the color of an object.

• Volume is the weight of an object.

• Volume is the height of an object.

What is the formula for calculating density?

• Density = Mass x Volume

• Density = Mass - Volume

• Density = Volume / Mass

• Density = Mass / Volume

When an object is less dense than the fluid it is in, what property allows it to float?

• Weight

• Density

• Buoyancy

• Inertia

What is the upward force exerted by a fluid on an object immersed in it called?

• Floating force

• Buoyant force

• Sinkage force

• Aqua lift

What is the phenomenon where an object falls freely under the influence of gravity?

• Downward drift

• Free fall

• Free dive

• Gravity drop

What is the acceleration due to gravity on Earth?

• 10.5 m/s^2

• 8.2 m/s^2

• 12.3 m/s^2

• 9.81 m/s^2

How does the mass of an object affect its free fall acceleration?

• The mass of an object does not affect its free fall acceleration.

• The mass of an object increases its free fall acceleration.

• The mass of an object affects the direction of its free fall acceleration.

• The mass of an object decreases its free fall acceleration.

What is the formula to calculate the distance an object falls in free fall?

• d = 0.5 * g * t

• d = 0.5 * g * t^2

• d = 0.5 * g / t

• d = g * t^2
