Concepts/Relationships: Net Force, Mass and Acceleration

Front

What is Net Force?

Back

Net Force is the overall force acting on an object when all the individual forces acting on it are combined. It determines the object's acceleration.

Front

What is the formula to calculate Net Force?

Back

Net Force (F_net) = Mass (m) × Acceleration (a)

Front

What is Mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg). It does not change regardless of the object's location.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²). It indicates how quickly an object is speeding up or slowing down.

Front

What is the relationship between Net Force, Mass, and Acceleration?

Back

According to Newton's Second Law, the Net Force acting on an object is equal to the mass of the object multiplied by its acceleration (F_net = m × a).

Front

What is Normal Force?

Back

Normal Force is the support force exerted upon an object that is in contact with a surface. It acts perpendicular to the surface.

Front

If an object is at rest on a flat surface, what is the Normal Force equal to?

Back

The Normal Force is equal to the weight of the object when it is at rest on a flat surface.

Front

How do you calculate the weight of an object?

Back

Weight (W) = Mass (m) × Gravitational Acceleration (g), where g is approximately 9.81 m/s² on Earth.

Front

What happens to the Net Force if all forces acting on an object are balanced?

Back

If all forces are balanced, the Net Force is zero, and the object will remain at rest or continue to move at a constant velocity.

Front

What is the unit of Force?

Back

The unit of Force is the Newton (N).
