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 = ma.

Front

What does the letter 'F' represent in the formula F = ma?

Back

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

Front

What does the letter 'm' represent in the formula F = ma?

Back

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

Front

What does the letter 'a' represent in the formula F = ma?

Back

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

Front

How do you calculate the mass of an object using Newton's 2nd Law?

Back

Mass can be calculated using the formula m = F/a, where F is the net force and a is the acceleration.

Front

If a force of 50 N is applied to an object and it accelerates at 10 m/s², what is the mass of the object?

Back

m = F/a = 50 N / 10 m/s² = 5 kg.

Front

What unit is force measured in?

Back

Force is measured in Newtons (N).

Front

What unit is mass measured in?

Back

Mass is measured in kilograms (kg).

Front

What unit is acceleration measured in?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

If an object has a mass of 2 kg and is subjected to a force of 10 N, what is its acceleration?

Back

a = F/m = 10 N / 2 kg = 5 m/s².
