newtons second law of motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

What is the formula to calculate force?

Back

Front

What does acceleration mean in physics?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

If an object has a mass of 5 kg and is accelerating at 2 m/s², what is the force acting on it?

Back

The force is 10 N, calculated using the formula F = ma (F = 5 kg * 2 m/s²).

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

When a constant force is applied, an increase in mass results in a decrease in acceleration.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a box has a mass of 10 kg and requires a force of 90 N to move, what is its acceleration?

Back

The acceleration is 9 m/s², calculated using the formula a = F/m (a = 90 N / 10 kg).

Front

What happens to the acceleration of an object if the force acting on it is doubled while its mass remains constant?

Back

The acceleration will also double, according to Newton's Second Law (F = ma).

Front

What is inertia?

Back

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