The force is the sum of all the forces that act upon an object
11Alexandr11 [23.1K]

Net force or resultant force

Explanation:

The net force or resultant force is the sum of all the forces that acts upon an object. Such forces are able to cause a push or pull on the body.

There are different kinds of forces prevalent on a body at rest and in motion.

A body is acted upon by frictional force and it has its own inertia which makes it resist motion.

Some other types of forces aids motion.

The newton's law of motion gives a very good insight into forces.

What is an object doing at the moment its instantaneous acceleration is zero?
Oliga [24]

Answer: Option A

Explanation:

Acceleration is defined as the rate of change of the vellocity.

Then, if the acceleration is equal zero, the object has a constant velocity or a velocity equal to zero (also constant, of course)

Then, te correct option would be option A; resting, because an object resting has instantaneuos acceleration of zero.

Hi there!

We know that:

U (Potential energy) = mgh

We are given the potential energy, so we can rearrange to solve for h (height):

U/mg = h

g = 9.81 m/s²

m = 30 g ⇒ 0.03 kg

0.062/(0.03 · 9.81) = 0.211 m
