Effects of Gravity and Air Resistance

How does gravity affect objects?

• Gravity pushes objects away from each other.

• Gravity has no effect on objects.

• Gravity affects objects by pulling them towards each other.

• Gravity only affects large objects like planets.

How does air resistance affect falling objects?

• Air resistance increases the speed of falling objects.

• Air resistance is the force that opposes the motion of falling objects.

• Air resistance has no effect on falling objects.

• Air resistance causes falling objects to accelerate faster.

What is free fall?

• Free fall is the motion of an object when only the gravitational force is present.

• Free fall occurs when an object is thrown upwards against gravity.

• Free fall is the motion of an object in a vacuum with no forces acting on it.

• Free fall happens when an object is at rest on the ground.

What is terminal velocity?

• The maximum speed an object can reach in a vacuum.

• The constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

• The speed at which an object stops accelerating due to gravity.

• The speed of sound in a given medium.

What role does air resistance play in determining the speed of a falling object?

• Air resistance has no effect on the speed of a falling object.

• Air resistance increases the speed of a falling object.

• Air resistance slows down the speed of a falling object, and the greater the air resistance, the slower the object falls.

• Air resistance only affects the direction of the falling object.

How does mass affect the gravitational force between two objects?

• The gravitational force between two objects decreases with the mass of the objects.

• The gravitational force between two objects remains constant regardless of the mass of the objects.

• The gravitational force between two objects increases with the mass of the objects.

• The gravitational force between two objects is only affected by the distance between them.
