Unit 4 - Falling Objects

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a falling object eventually reaches when the resistance of the medium (like air) prevents further acceleration.

Front

What happens to a falling object when it reaches terminal velocity?

Back

When a falling object reaches terminal velocity, it stops accelerating and falls at a constant speed.

Front

What force causes objects to fall towards the Earth?

Back

Gravity is the force that causes objects to fall towards the Earth.

Front

What is the role of air resistance in falling objects?

Back

Air resistance opposes the motion of falling objects and increases with speed, eventually balancing the force of gravity at terminal velocity.

Front

What is a parachute designed to maximize?

Back

A parachute is designed to maximize air resistance to slow down the descent of a person or object.

Front

What happens to the velocity of a person falling from a high-flying airplane?

Back

The velocity will increase until reaching terminal velocity, at which point it becomes relatively constant.

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object, which does not change regardless of location.

Front

How does the atmosphere affect falling objects?

Back

The atmosphere provides air resistance, which affects the acceleration and speed of falling objects.

Front

What is the effect of a parachute opening on a falling object's speed?

Back

When a parachute opens, it increases air resistance, causing the falling object's speed to decrease.

Front

What is the relationship between speed and air resistance for a falling object?

Back

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