Calculations Newton's 2nd law

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.

Front

What does the symbol 'F' represent in the equation F = m * a?

Back

'F' represents the net force applied to an object, measured in Newtons (N).

Front

What does the symbol 'm' represent in the equation F = m * a?

Back

'm' represents the mass of the object, measured in kilograms (kg).

Front

What does the symbol 'a' represent in the equation F = m * a?

Back

'a' represents the acceleration of the object, measured in meters per second squared (m/s²).

Front

If a force of 40 N is applied to a mass of 5 kg, what is the acceleration?

Back

The acceleration is 8 m/s² (using the formula a = F/m).

Front

How do you calculate the force if you know the mass and acceleration?

Back

Use the formula F = m * a, where F is force, m is mass, and a is acceleration.

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 10 kg and accelerates at 15 m/s², what is the force applied?

Back

The force applied is 150 N (using F = m * a).

Front

What is the mass of an object that experiences a force of 400 N and accelerates at 4 m/s²?

Back

The mass of the object is 100 kg (using m = F/a).

Front

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

Back

The acceleration decreases, as acceleration is inversely proportional to mass.
