The scientist to first introduce the concept of inertia by thinking about friction was
Galileo

A sheet of paper can be withdrawn from under a container of milk without toppling it if the paper is jerked quickly. This best demonstrates that
the milk carton has inertia.

An object in mechanical equilibrium is an object
that can be at rest or moving at a constant speed

The force of friction on a sliding object is 10 N. The applied force needed to maintain a constant velocity is
10 N

A package falls off a truck that is moving at 30 m/s. Neglecting air resistance, the horizontal speed of the package just before it hits the ground is
about 30 m/s

If your automobile runs out of fuel while you are driving, the engine stops but you do not come to an abrupt stop. The concept that most explains why is
Inertia

According to Newton's law of inertia, a railroad train in motion should continue going forever even if its engine is turned off. We never observe this because railroad trains
always have forces that oppose their motion.

Whirl a rock at the end of a string and it follows a circular path. If the string breaks, the tendency of the rock is to
follow a straight-line path.

When a rocket ship accelerating in outer space runs out of fuel, it
no longer accelerates.

If no external forces are acting on a moving object, it will
continue moving at the same velocity.

Your inertia can be measured relative to another person by looking at their
mass

If Joe has a mass of 100 kg, and Betty has a mass of 50 kg, who has more Inertia?
Joe

If I fling a rock into space, beyond the gravity of the earth, it will stop...
when it hits something to provide a force

Who made the three laws of motion?
Newton
