Newton's Laws

Front

What is the SI unit of acceleration?

Back

m/s²

Front

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron?

Back

same

Front

An object has more inertia because it has more...

Back

mass

Front

If the man pushes with an equal amount of force, which object will accelerate more?

Back

Lawnmower because it has less mass

Front

One object has twice as much mass as another object. The first object also has also twice as much...

Back

inertia

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

Define inertia.

Back

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

Front

How does mass affect acceleration when a constant force is applied?

Back

Greater mass results in less acceleration when the same force is applied.
