8.6A Net Forces and FMA

Front

What is the net force?

Back

The net force is the total force acting on an object, taking into account both the magnitude and direction of all individual forces. It determines the object's acceleration.

Front

If two forces are acting in the same direction, how do you calculate the net force?

Back

You add the magnitudes of the forces together. For example, if one force is 10 N right and another is 5 N right, the net force is 15 N right.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = m × a, where m is mass and a is acceleration.

Front

What unit is used to measure force?

Back

The unit of force is the Newton (N).

Front

If a force of 10 N is applied to an object with a mass of 2 kg, what is the acceleration?

Back

Using F = m × a, acceleration (a) = F/m = 10 N / 2 kg = 5 m/s².

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero because the forces cancel each other out.

Front

How does mass affect acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases for a constant force, according to F = m × a.

Front

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

Back

The relationship is described by Newton's second law: Force equals mass times acceleration (F = m × a).

Front

If a 4 kg object is accelerating at 2 m/s², what is the net force acting on it?

Back

Using F = m × a, the net force is F = 4 kg × 2 m/s² = 8 N.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
