Newton's Laws of Motion

Front

What is Fluid Friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas). It is the force that opposes the motion of the object in the fluid.

Front

How many laws of motion did Sir Isaac Newton discover?

Back

Sir Isaac Newton discovered 3 laws of motion.

Front

What are the ways to reduce friction?

Back

Friction can be reduced by: 1) Reducing the force acting between the two surfaces, 2) Reducing the roughness of the surfaces, 3) Using lubricants like wax, grease, or oil.

Front

What does Newton's 1st Law of Motion state?

Back

Newton's 1st Law of Motion states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What does Newton's 2nd Law of Motion state?

Back

Newton's 2nd Law of Motion states that 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 does Newton's 3rd Law of Motion state?

Back

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

What is an example of Newton's 3rd Law of Motion?

Back

An example of Newton's 3rd Law is when a rocket launches: it pushes gases down (action) and moves up (reaction).

Front

What is the reaction force when a cannon fires a cannonball?

Back

The reaction force is the cannon moving backwards.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move when a force is applied.

Front

What is sliding friction?

Back

Sliding friction is the resistance encountered when two surfaces slide against each other.
