Unit 3 Newton's Second Law of Motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula F = ma.

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to acceleration if mass increases while the force remains constant?

Back

If mass increases while the force remains constant, the acceleration decreases.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

How does mass affect acceleration when a constant force is applied?

Back

Mass and acceleration have an inverse relationship; as mass increases, acceleration decreases for a constant force.

Front

What is the relationship between force and acceleration?

Back

Force and acceleration have a direct relationship; as force increases, acceleration increases if mass remains constant.

Front

If a box has a mass of 10 kg and is accelerated at 9 m/s², what is the force applied?

Back

The force applied is 90 N (using F = ma: F = 10 kg * 9 m/s²).

Front

Which will accelerate more with the same applied force: a lighter object or a heavier object?

Back

A lighter object will accelerate more than a heavier object when the same force is applied.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can reduce the acceleration of an object.

Front

What is inertia?

Back

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