Dynamics A

Front

What does Newton's first law state?

Back

Objects in uniform motion will remain that way unless acted on by an unbalanced force.

Front

What is inertia?

Back

Inertia refers to how much an object resists change to its state of motion (or obeys Newton's first law).

Front

What is mass?

Back

Mass is the measurement of how much matter an object is composed of.

Front

What is weight?

Back

Weight is a force that measures the gravitational pull on an object.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = m × g).

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.8 m/s².

Front

How does mass affect inertia?

Back

An increase in mass results in greater inertia, making it harder to change the object's state of motion.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force is equal to mass times acceleration (F = m × a).

Front

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate or change its motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
