Why is the force needed to pull a backpack up increases as it gets higher and higher?
As the backpack gets higher, the distance over which you are lifting it increases, requiring more work to overcome gravity. The force needed to lift the backpack is directly proportional to the distance it is lifted and the weight of the backpack. This is due to the gravitational force acting on the backpack.
When two forces are acting in the opposite direction how do you calculate the net force?
To calculate the net force when two forces are acting in opposite directions, subtract the smaller force from the larger force. The direction of the net force will be in the direction of the larger force.
What is the measure of the force of gravity of acting on an object?
The force of gravity acting on an object is determined by the mass of the object and the acceleration due to gravity (9.81 m/s^2 on Earth). The formula to calculate the force of gravity is F = m * g, where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity.
What type of force does a backpack exert on the body?
A backpack exerts a downward force on the body due to gravity pulling it downward. Additionally, the straps of the backpack exert a force on the shoulders and back to support the weight of the backpack.
How to calculate g force in a given scenario?
To calculate g-force in a given scenario, you can use the formula: g-force acceleration due to gravity (9.81 m/s2) / acceleration in the scenario. This will give you the number of times the force of gravity is acting on an object in that scenario.

How does the size of an object affect the force of gravity acting upon it?
The force of gravity acting on an object is directly proportional to its mass. This means that the larger the object, the greater the force of gravity acting upon it.
Why are you not doing any work when you are carring your backpack to class at a constant speed?
If the backpack is being carried at a constant speed, there is no change in velocity, which means there is no net force acting on it. Since work is the result of a force acting over a distance, and no force is causing the backpack to accelerate or decelerate, no work is being done on the backpack.
When apple is falling the gravitational force is acting but why force of gravity is not acting here?
The terms "gravitational force" and "force of gravity" are interchangeable and both refer to the same force exerted on objects due to gravity. When an apple is falling, the force of gravity (gravitational force) is indeed acting on it, causing it to accelerate towards the Earth.
How do you calculate the mass of an object using a Newton meter?
To calculate the mass of an object using a Newton meter, you would measure the force of gravity acting on the object in Newtons, and then divide this force by the acceleration due to gravity (9.8 m/s^2) to find the mass in kilograms. The formula is mass = force of gravity / acceleration due to gravity.
How weight and force related?
Weight is the force exerted on an object by gravity, measured in newtons (N). The force of gravity acting on an object determines its weight. The formula to calculate weight is weight = mass x gravity, where mass is the amount of matter in an object and gravity is the acceleration due to gravity.
How do you calculate pulley force needed?
To calculate the force needed on a pulley system, you can use the formula: Force = (mass * acceleration) + (mass * gravity), where mass is the load being moved, acceleration is the desired speed at which the load should move, and gravity is the force due to gravity acting on the load. By considering these factors, you can determine the force required to move the load with the pulley system.
Measure of force of gravity acting in an object?
The measure of the force of gravity acting on an object is its weight. Weight is the force exerted by gravity on the mass of an object, and it is typically measured in units such as pounds or newtons. The weight of an object can vary depending on the strength of the gravitational field acting upon it.
