Physics Vocabulary

What is gravity?

• The force that pushes objects away from each other

• A noncontact attractive force that exists between all objects that have mass

• The force that only affects objects on Earth

• A type of magnetic force between planets

What causes the periodic rise and fall of the ocean's surface known as tides?

• The gravitational pull of the Sun only

• The rotation of the Earth on its axis

• The gravitational force between the Moon and Earth

• The atmospheric pressure changes

What are spring tides?

• Tides that occur during the spring season

• Higher than normal high tides

• Lower than normal low tides

• Tides that bring in spring water from the ocean

When do neap tides occur?

• When the moon is in a new or full moon phase

• When the moon is in a first quarter or third quarter moon phase

• When the Earth is at its closest point to the Sun

• During a solar eclipse

What is a force?

What is a balanced force?

• A force that causes an object to start moving.

• When the net force of an object is ON, and the object's motion does not change.

• A force that always causes an object to accelerate.

• The force that acts in the direction of motion.

What happens when an unbalanced force acts on an object?

• The object's motion does not change.

• The object will come to a complete stop.

• Unbalanced forces cause objects to change their motion, or accelerate.

• The object will always move at a constant velocity.

What is the definition of motion in physics?

• The process of applying force.

• The interaction between two objects.

• The process of changing position.

• The resistance to movement between two objects.
