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, in accordance with Newton's first law.

Front

How is mass defined in physics?

Back

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

Front

What is the definition of weight?

Back

Weight is a force that results from the gravitational pull on an object's mass.

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and the acceleration due to gravity (W = m * g).

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

How does inertia affect motion?

Back

Inertia causes an object to maintain its state of motion unless acted upon by an unbalanced force.

Front

What units are used to measure mass?

Back

Mass is typically measured in kilograms (kg) or grams (g).

Front

What units are used to measure weight?

Back

Weight is measured in newtons (N) or pounds (lb).

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × acceleration due to gravity (g).
