PS 2-1 | Newton's 2nd Law Calculation Check

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = m * a.

How do you calculate net force if mass and acceleration are known?

Back

Net force can be calculated using the formula: F = m * a, where 'F' is the net force, 'm' is the mass, and 'a' is the acceleration.

If an object has a mass of 5 kg and accelerates at 10 m/s², what is the net force?

Back

The net force is 50 N (calculated as F = 5 kg * 10 m/s²).

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

Back

The unit of force in the SI system is the newton (N).

Front

If a force of 20 N is applied to a mass of 4 kg, what is the acceleration?

Back

The acceleration is 5 m/s² (calculated as a = F/m = 20 N / 4 kg).

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, and vice versa.

What is the formula to find acceleration if force and mass are known?

Back

The formula to find acceleration is: a = F/m, where 'F' is the net force and 'm' is the mass.
