Newton's Laws Review

Front

What is the formula to calculate Force?

Back

Force = mass x acceleration (F = m x a)

Front

What type of forces are acting on a marble that speeds up while rolling down a ramp?

Back

Unbalanced forces

Front

Which law explains why more force is needed to accelerate an object with more mass?

Back

Newton's second law, the law of acceleration

Front

What is the unit of measurement for Force?

Back

Newton (N)

Front

What does Newton's 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

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 according to Newton's second law?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Force / mass (a = F / m)

Front

What is the significance of balanced forces?

Back

Balanced forces result in no change in motion; the object remains at rest or continues to move at a constant velocity.

Front

What is the law of universal gravitation?

Back

Every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
