Newton's Second Law

Front

What is Newton's Second Law of Motion?

Back

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

Front

How do you calculate force using mass and acceleration?

Back

Force can be calculated using the formula F = mass * acceleration.

Front

If an object has a mass of 5 kg and is accelerated at 3 m/s², what is the force acting on it?

Back

The force is 15 N (F = 5 kg * 3 m/s²).

Front

What unit is force measured in?

Back

Force is measured in Newtons (N).

Front

What is the relationship between mass, acceleration, and force?

Back

The relationship is described by Newton's Second Law: Force is directly proportional to both mass and acceleration.

Front

If two objects have the same acceleration, how does their mass affect the force required?

Back

The object with greater mass will require a greater force to achieve the same acceleration.

Front

What is the force required to accelerate a 10 kg object at 2 m/s²?

Back

The required force is 20 N (F = 10 kg * 2 m/s²).

Front

If a 20 kg bike accelerates at 10 m/s², what is the force acting on it?

Back

The force is 200 N (F = 20 kg * 10 m/s²).

Front

What happens to the force if the mass of an object is doubled while keeping acceleration constant?

Back

The force will also double, as force is directly proportional to mass (F = ma).

Front

What is the effect of increasing acceleration on the force required for a given mass?

Back

Increasing acceleration will increase the force required, as force is directly proportional to acceleration (F = ma).
