Air Resistance / Gravity

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, acting in the opposite direction to the object's movement.

Front

How does air resistance affect falling objects?

Back

Air resistance slows down the acceleration of falling objects, eventually leading to a constant speed known as terminal velocity.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, with the Earth exerting a gravitational pull on objects, causing them to fall.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed reached by an object when the force of air resistance equals the force of gravity acting on it.

Front

What role does a parachute play in air resistance?

Back

A parachute increases air resistance, allowing a person or object to fall more slowly by creating a larger surface area for air to push against.

Front

In which direction does air resistance act on a falling object?

Back

Air resistance acts upward, opposing the downward force of gravity.

Front

What factors affect air resistance?

Back

Air resistance is affected by the object's speed, shape, and surface area, as well as the density of the air.

Front

What is the relationship between speed and air resistance?

Back

As the speed of an object increases, the air resistance acting on it also increases.

Front

How does the shape of an object influence air resistance?

Back

Streamlined shapes reduce air resistance, while blunt shapes increase it, affecting how quickly an object can move through the air.

Front

What is the difference between weight and mass?

Back

Weight is the force of gravity acting on an object, while mass is the amount of matter in an object, measured in kilograms.
