Real World Science: Forces Flashcard

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

Who is known for the three laws of motion?

Back

Isaac Newton is known for formulating the three laws of motion.

Front

What is pressure in terms of forces?

Back

Pressure is the force that acts perpendicular to the surface of an object.

Front

What is electromagnetism?

Back

Electromagnetism is the force that acts at a distance and is responsible for the attraction between magnets.

Front

What force pulls objects towards the Earth?

Back

Gravity is the force that pulls objects towards the Earth.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or direction, causing a change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is the role of gravity in our daily lives?

Back

Gravity keeps us grounded on Earth and affects how objects fall.

Front

What is an example of a balanced force?

Back

An example of balanced forces is when two people push a car from opposite sides with equal strength.
