Newton's Laws

Front

What is the unit of measurement for force?

Back

Newtons

Front

A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s^2. Determine the mass of the encyclopedia.

Back

m = 30 kg

Front

What does an unbalanced force mean for an object?

Back

An unbalanced force means that an object is changing its motion.

Front

What type of friction occurs when air pushes against a moving object causing it to negatively accelerate?

Back

Air resistance

Front

What type of friction do swimming fish experience?

Back

Fluid Friction

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second 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 Third Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
