8.6A Net Forces and FMA

Front

What is net force?

Back

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

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction. If forces are in opposite directions, subtract the smaller force from the larger one.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

What is the acceleration of an object with a net force of 20 N and a mass of 4 kg?

Back

5 m/s² (using the formula a = F/m).

Front

What happens to an object at rest when no net force acts on it?

Back

An object at rest will remain at rest if no net force acts on it, according to Newton's First Law of Motion.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

The greater the mass of an object, the less acceleration it will have when the same force is applied, according to Newton's Second Law.

Front

What is gravitational force?

Back

Gravitational force is the force of attraction between two masses, such as the Earth and an object.

Front

How do you calculate the weight of an object?

Back

Weight (W) = Mass (m) × Gravitational acceleration (g), where g is approximately 9.8 m/s² on Earth.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the object's mass.
