Newton's Second Law of Motion

Click on the flashcard to see the answer

What is Newton's Second Law of Motion?

It states that the force acting on an object is equal to the mass of the object times its acceleration (F = ma).

What does the equation F = ma mean?

Force (F) applied is equal to mass (m) multiplied by acceleration (a).

In which units is force measured?

Force is measured in Newtons (N).

How does mass affect acceleration if the force is constant?

If the force is constant, increasing the mass will decrease the acceleration.

Give an example of Newton's Second Law in everyday life.

Pushing a car requires more force to accelerate compared to a small bicycle.

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

The 'a' represents acceleration, which is the change in velocity over time.

What happens to acceleration if force increases while mass remains constant?

Acceleration will increase because they are directly proportional.

What is the SI unit of mass when using the formula F = ma?

The SI unit of mass is the kilogram (kg).

How can Newton's Second Law be applied to airplanes?

Airplanes need a greater thrust to overcome mass and accelerate for takeoff.

Why does a loaded truck require more force to accelerate than an empty one?

A loaded truck has more mass, requiring more force to achieve the same acceleration.

How does friction affect Newton's Second Law?

Friction acts as a force that needs to be overcome to accelerate an object.

What role does net force play in Newton's Second Law?

Net force is the sum of all forces acting on an object and determines acceleration.

Describe a scenario where there is no acceleration.

There is no acceleration when the forces on an object are balanced, resulting in zero net force.

How can you increase acceleration without changing mass?

By increasing the force applied to the object.

What is the relationship between acceleration and velocity in Newton's Second Law?

Acceleration is the rate of change of velocity; they are related but not the same.
