Force (Newton's 2nd Law: Acceleration)

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 formula F = m * a?

Back

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

Front

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

Back

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

Front

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

Back

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

Front

If a truck has a mass of 10 kg and accelerates at 3 m/s², what is the force applied?

Back

30 Newtons (calculated using F = m * a: F = 10 kg * 3 m/s²).

Front

How do you calculate force using mass and acceleration?

Back

Force is calculated using the formula F = m * a, where 'F' is force, 'm' is mass, and 'a' is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 1 kg golf ball accelerates at 25 m/s², what force is applied to it?

Back

25 Newtons (calculated using F = m * a: F = 1 kg * 25 m/s²).

Front

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

Back

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

Front

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

Back

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