Force calculations

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

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.

Front

What happens to the acceleration of an object if its mass increases while the force applied remains constant?

Back

The acceleration decreases.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a) or F = m × a.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 20 kg object accelerates at 10 m/s², what is the force applied?

Back

200 Newtons (F = m × a = 20 kg × 10 m/s²).

Front

What is the unit of mass?

Back

The unit of mass is the kilogram (kg).

Front

How do you find the acceleration of an object?

Back

Acceleration (a) = net force (F) / mass (m).

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues moving at a constant velocity.

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.
