What is Newton's Second Law of Motion?
Click to flip
It states that the force acting on an object is equal to the mass of the object times its acceleration (F = ma).
Click to flip
What does the equation F = ma mean?
Click to flip
Force (F) applied is equal to mass (m) multiplied by acceleration (a).
Click to flip
In which units is force measured?
Click to flip
Force is measured in Newtons (N).
Click to flip
How does mass affect acceleration if the force is constant?
Click to flip
If the force is constant, increasing the mass will decrease the acceleration.
Click to flip
Give an example of Newton's Second Law in everyday life.
Click to flip
Pushing a car requires more force to accelerate compared to a small bicycle.
Click to flip
What does 'a' represent in the formula F = ma?
Click to flip
The 'a' represents acceleration, which is the change in velocity over time.
Click to flip
What happens to acceleration if force increases while mass remains constant?
Click to flip
Acceleration will increase because they are directly proportional.
Click to flip
What is the SI unit of mass when using the formula F = ma?
Click to flip
The SI unit of mass is the kilogram (kg).
Click to flip
How can Newton's Second Law be applied to airplanes?
Click to flip
Airplanes need a greater thrust to overcome mass and accelerate for takeoff.
Click to flip
Why does a loaded truck require more force to accelerate than an empty one?
Click to flip
A loaded truck has more mass, requiring more force to achieve the same acceleration.
Click to flip
How does friction affect Newton's Second Law?
Click to flip
Friction acts as a force that needs to be overcome to accelerate an object.
Click to flip
What role does net force play in Newton's Second Law?
Click to flip
Net force is the sum of all forces acting on an object and determines acceleration.
Click to flip
Describe a scenario where there is no acceleration.
Click to flip
There is no acceleration when the forces on an object are balanced, resulting in zero net force.
Click to flip
How can you increase acceleration without changing mass?
Click to flip
By increasing the force applied to the object.
Click to flip
What is the relationship between acceleration and velocity in Newton's Second Law?
Click to flip
Acceleration is the rate of change of velocity; they are related but not the same.
