[Answer] What is the net force on a bag pulled down by gravity with a force of 18 newtons and pulled upward by a rope with a force of 18 newtons?

Answer: zero
What is the net force on a bag pulled down by gravity with a force of 18 newtons and pulled upward by a rope with a force of 18 newtons?

For example an object on a level surface is pulled (attracted) downward toward the center of the Earth by the force of gravity . At the same time a force is applied by the surface that resists the downward force with equal upward force (called a normal force ). The situation produces zero net force …

The gravitational force equivalent or more commonly g- force is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight with a g- force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth g of about 9.8 m/s 2. Since g-forces indirectly produce weight any g- force can be …

The gravitational force pulling down on the mass is no longer equal to the upward elastic force of the spring. In the terminology of the previous section F 1 and F 3 are no longer equal. However it is still true that F 1 = F 2 and F 3 = F 4 as this is required by Newton’s third law.

An inclined plane also known as a ramp is a flat supporting surface tilted at an angle with one end higher than the other used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods …

Tension in a string is a scalar quantity (i.e. non-negative). Zero tension is slack. A string or rope is often idealized as one dimension having length but being massless with zero cross section.If there are no bends in the string as occur with vibrations or pulleys then tension is a …
