Forces/Free Body Diagrams (L1)

Front

What is Thrust Force?

Back

Thrust Force (Th) involves self-movement of objects (rockets, people walking, animals running) or movement of objects with engines (cars, planes).

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the net force acting on an object is zero, resulting in constant speed or no movement.

Front

What is Lift Force?

Back

Lift Force (L) is an upward force due to the motion of objects with wings (birds, planes, helicopters).

Front

What is Buoyant Force?

Back

Buoyant Force (B) refers to the upward force that allows objects to float in a liquid or air due to density.

Front

What does it mean if an object is accelerating?

Back

If an object is accelerating, the forces acting on it are unbalanced, resulting in a change in speed or direction.

Front

What is the relationship between speed and balanced forces?

Back

When an object is moving at a constant speed, the forces acting on it are balanced.

Front

What is an example of an object experiencing Thrust Force?

Back

A rocket launching into space is an example of an object experiencing Thrust Force.

Front

How does Lift Force affect airplanes?

Back

Lift Force allows airplanes to rise off the ground and stay in the air by counteracting the force of gravity.

Front

What is the role of Buoyant Force in swimming?

Back

Buoyant Force helps swimmers float and stay on the surface of the water.

Front

What happens to an object when the forces acting on it are unbalanced?

Back

The object will accelerate in the direction of the net force.
