Exploring Ocean Forces Lesson 1

Forces acting on an object that are equal in size but act in opposite directions, resulting in no change of movement are ______________________

• motion

• balanced forces

• unbalanced forces

• force

Forces (pushes and pulls) that are not equal to one another.

• motion

• balanced forces

• unbalanced forces

• force

Something that remains constant and unchanged in an investigation

• independent variable

• balanced forces

• force

• control variable

__________ is a push or a pull that causes an object to change its motion (that is, start moving, stop moving, or change direction)

• independent variable

• balanced forces

• force

• control variable

An investigation where all things are kept the same apart from one thing, called the independent variable

• independent variable

• dependent variable

• force

• fair test

The amount of matter in an object, measured in kilograms

• inertia

• dependent variable

• force

• mass

The act or process of changing position or location

• inertia

• motion

• force

• mass

Something that is changed in an investigation

• inertia

• motion

• independent variable

• mass

Something in an investigation that is being tested and depends on the independent variable.

• dependent variable

• motion

• independent variable

• mass
