Newton's Laws

Front

What is Fluid Friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas). It affects the speed and motion of swimming fish.

Front

How does friction affect speed?

Back

More friction decreases speed, while less friction increases speed.

Front

What does 'Forces come in pairs' represent?

Back

This represents Newton's 3rd law of motion, which states that for every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

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

Front

Which rock requires the most force to stop: a 10 kg, 15 kg, or 20 kg rock?

Back

The 20 kg rock requires the most force to stop due to its greater mass.

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 at a constant velocity unless acted upon by a net external 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 the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more.

Front

What is static friction?

Back

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