Newton's Laws

Front

What does Newton's 1st Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is inertia in the context of Newton's 1st Law?

Back

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

Front

Provide an example of Newton's 1st Law in everyday life.

Back

A pencil remains on a desk until someone picks it up.

Front

Explain the relationship between force, mass, and acceleration.

Back

Force equals mass times acceleration (F=ma), meaning that a greater force results in greater acceleration if mass is constant.

Front

What happens to a lighter truck compared to a heavier truck when both accelerate?

Back

The lighter truck accelerates more quickly than the heavier truck when the same force is applied.

Front

How does Newton's 3rd Law apply to a fireman using a hose?

Back

When the fireman pushes water out of the hose (action), he is pushed backward (reaction).

Front

What is the significance of the net force in Newton's 2nd Law?

Back

The net force is the total force acting on an object, which determines its acceleration.
