Force and Motion Vocabulary

The movement of energy from one object to another.

• equal force

• energy transfer

• friction

• gravity

• motion

Answer explanation

The correct answer is 'energy transfer' because it specifically describes the movement of energy from one object to another, unlike the other options which refer to different concepts.

Forces that act together in an object without changing its motion are called_______________.

Answer explanation

Forces that act together without changing an object's motion are called equal forces. They balance each other out, resulting in no net force and maintaining the object's state of motion.

friction

• Forces that have the same magnitude and act in opposite directions.

• The process by which energy is relocated from one system to another.

• A force between surfaces that slows objects or stops them from moving.

• The force that attracts the body toward the center of the earth, or toward any other physical body having mass.

Answer explanation

Friction is a force that occurs between surfaces, acting to slow down or stop the motion of objects. This makes the correct choice "A force between surfaces that slows objects or stops them from moving."

A non-contact force that pulls objects.

• friction

• act

• motion

• gravity

• equal forces

Answer explanation

Gravity is a non-contact force that pulls objects towards each other, such as the Earth pulling objects towards its center. Unlike friction, which requires contact, gravity acts at a distance.

____________ is the action or process of moving or being moved.

• motion

• unequal forces

• gravity

• energy transfer

Answer explanation

Motion is defined as the action or process of moving or being moved. It directly relates to the concept of movement, making it the correct choice among the options provided.

Forces that do not cancel each other out and that cause an object to change its motion.

• Equal forces

• Gravity

• interaction

• patterns of motion

• unequal forces

Answer explanation

Unequal forces are those that do not cancel each other out, leading to a change in an object's motion. In contrast, equal forces balance each other, resulting in no motion change.

To have contact with something through touch or actions.

• act

• control

• gravity

• interaction

• patterns of motion

Answer explanation

The term 'interaction' refers to having contact with something through touch or actions, making it the correct choice. Other options like 'act' and 'control' do not specifically convey this meaning.

effect

• Reciprocal act or influence.

• The action or process of moving or changing place or position.

• A change that results when something is done or happening.

• An invisible force that pulls objects towards each other.

Answer explanation

The correct choice, 'A change that results when something is done or happening,' accurately defines 'effect' as it refers to the outcome or result of an action, distinguishing it from other options that describe different concepts.

___________________ is an idea or explanation that you then test through study and experimentation.

• motion

• hypothesis

• friction

• gravity

Answer explanation

A hypothesis is a proposed explanation that can be tested through study and experimentation, making it the correct choice. Other options like motion, friction, and gravity are concepts, not testable ideas.

The repeated process of an object moving.

• patterns of motion

• motion

• equal forces

• unequal forces

Answer explanation

The phrase 'the repeated process of an object moving' describes 'patterns of motion', which refers to the regular and predictable ways in which objects move over time. Other options do not capture this concept.
