Forces

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m)

Front

If a 50 kg object is pushed with a force of 500 N, what is its acceleration?

Back

10 m/s²

Front

What do unbalanced forces cause?

Back

Unbalanced forces cause motion.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How does mass affect acceleration?

Back

For a given force, an increase in mass results in a decrease in acceleration.

Front

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

Back

This relationship is described by Newton's second law: F = m * a.

Front

What is the acceleration of an object with a mass of 8 kg experiencing a net force of 16 N?

Back

2 m/s²

Front

What is the net force acting on a 74 kg person experiencing an acceleration of -2.2 m/s²?

Back

-162.8 N.

Front

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

Back

It remains at rest due to inertia.
