Flashcard: 3 Laws of Motion

Front

Newton’s first law of motion is also called the law of ________?

Back

Inertia

Front

What are examples of unbalanced forces?

Back

A car speeding up, a dog slowing down, and a person turning around the block.

Front

Force is directly proportional to acceleration but inversely proportional to an object's mass. This is known as the:

Back

Law of Acceleration

Front

Why does a passenger move forward when slamming on the brakes in a moving car?

Back

The passenger has the inertia to keep moving forward.

Front

Calculate the mass of a chair if a 260.5N unbalanced force causes an acceleration of 4.2 m/s².

Back

62.02 kg

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What does Newton's second law of motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

What is an example of balanced forces?

Back

A book resting on a table, where the force of gravity is balanced by the normal force of the table.
