Newton's Laws

Front

What is Newton's 1st Law of Motion?

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

Define inertia.

Back

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

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 swimming demonstrate Newton's 3rd Law of Motion?

Back

When a swimmer pushes water backward, the water pushes the swimmer forward.

Front

What is the formula to calculate force?

Back

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

Front

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

Back

200 Newtons.

Front

What is the law of conservation of mass?

Back

Mass is neither created nor destroyed in a chemical reaction.

Front

Explain the concept of net force.

Back

Net force is the vector sum of all the forces acting on an object.

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.
