Gravity Vocabulary Quiz - G6

What is gravity?

• The resistance between two surfaces in motion.

• The force that pulls objects toward each other, especially toward the center of the Earth.

• The push or pull that causes an object to accelerate.

• The tendency of objects to resist changes in their state of motion.

What does it mean for objects to attract in terms of gravity?

• They push each other away due to friction.

• They pull toward each other.

• They increase in mass when close to each other.

• They reduce their inertia.

What is mass?

• The amount of gravitational pull an object experiences.

• The amount of matter in an object, which affects how much gravitational force it has.

• The force exerted on an object due to gravity.

• The rate at which an object accelerates when falling.

What is force?

• The resistance between two moving surfaces.

• The amount of matter in an object.

• A push or pull on an object that can cause it to move or change direction.

• The speed at which an object falls to the Earth.

What is an orbit?

• The rate at which an object speeds up.

• The curved path an object takes around another object due to gravity.

• The gravitational force pulling objects toward Earth.

• The resistance objects experience when falling.

Acceleration refers to:

• The speed at which an object moves over a surface.

• The rate at which an object’s velocity changes over time.

• The force exerted on an object due to gravity.

• The resistance to changes in motion.

What is the weight of an object?

• The amount of matter in an object.

• The force exerted on an object due to gravity, depending on mass and gravitational pull.

• The rate at which an object accelerates toward the Earth.

• The force of inertia acting on a moving object.

Which of the following best describes friction?

• The rate of acceleration due to gravity.

• The push or pull that causes an object to move.

• The resistance one surface encounters when moving over another.

• The tendency of an object to stay in motion.

What is inertia?

• The force that opposes gravity.

• The amount of matter in an object.

• The tendency of an object to resist changes in its state of motion.

• The force that pulls objects toward each other.

A Newton is:

• The unit of force in the metric system, named after Sir Isaac Newton.

• The measure of friction between two objects.

• The gravitational pull on an object.

• The rate of an object’s acceleration.
