Forces and Transportation

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid (like water) due to the upward force exerted by the fluid.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the center of the Earth or any other celestial body.

Front

What is thrust?

Back

Thrust is the force that propels an object forward, such as a rocket or airplane.

Front

What is lift?

Back

Lift is the force that acts perpendicular to the direction of motion and allows an object to rise in the air.

Front

What is drag?

Back

Drag is the resistance force that opposes the motion of an object through a fluid.

Front

How does gravity affect floating objects?

Back

Gravity pulls objects down, but if the buoyant force is greater than gravity, the object will float.

Front

What must thrust be greater than for a rocket to take off?

Back

Thrust must be greater than gravity for a rocket to fly.

Front

What is the relationship between lift and weight?

Back

Lift must be greater than weight for an object to ascend.

Front

What happens when drag increases?

Back

When drag increases, it slows down the motion of an object moving through a fluid.

Front

What is an example of buoyancy in everyday life?

Back

A boat floating on water is an example of buoyancy.
