G5_Force

Buoyancy

• A measure of the upward force a fluid exerts on an object when it is submerged.

• The weight of an object in air.

• The density of an object compared to water.

• The speed at which an object sinks in a fluid.

Weight

• The force of attraction on an object due to gravity.

• The mass of an object measured in kilograms.

• The amount of space an object occupies.

• The resistance of an object to changes in its state of motion.

Newton

• The unit of measurement for the weight of an object

• A type of force

• A measure of energy

• A unit of temperature

Rotation

• The movement of a celestial body around another body.

• The spinning of a celestial body around its own axis.

• The process of a celestial body moving through space without spinning.

• The change in position of a celestial body in relation to the stars.

Force meter

• An instrument used to measure weight.

• A device for measuring temperature.

• A tool for measuring speed.

• An apparatus for measuring distance.

Upthrust

• The downward force exerted by a fluid that acts with gravity.

• The upward force exerted by a fluid that acts opposite to gravity (or weight).

• The force that resists the motion of an object through a fluid.

• The force that increases the weight of an object in a fluid.

Revolution

• The process of a planet spinning on its axis.

• The orbital movement of Earth around the Sun. Earth takes 365 ¼ days to complete one revolution.

• The change in seasons due to the tilt of the Earth's axis.

• The movement of the Moon around the Earth.

Reason for an object to float on a liquid

• Upthrust is greater than or equal to gravity.

• The object is made of a denser material than the liquid.

• The liquid has a higher temperature than the object.

• The object is shaped like a boat.

Mass

• The amount of matter present in an object.

• The weight of an object in a vacuum.

• The volume of an object measured in liters.

• The density of an object calculated by mass divided by volume.

Reason for an object to sink in a liquid

• Upthrust is less than gravity

• The object is too large

• The liquid is too dense

• The object is made of rubber
