Science Fall Semester Review 6th

Front

What is the principle of equal and opposite forces?

Back

According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that when a person pushes back with a paddle, the water pushes back with an equal force, propelling the person forward.

Front

What are the three non-contact forces?

Back

The three non-contact forces are gravity, electricity, and magnetism.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, opposite to the crest.

Front

Can rocks change from one type to another?

Back

Yes, rocks can change from one type to another through processes like weathering, erosion, and metamorphism.

Front

What happens to temperature and pressure as you go deeper into the Earth?

Back

Temperature and pressure increase as you go deeper into the Earth.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is electricity?

Back

Electricity is a form of energy resulting from the existence of charged particles, which can produce an electric current.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, typically associated with magnets and magnetic fields.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical interaction between objects, while non-contact forces act at a distance without direct contact.

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.
