A desk weights 500 N with gravity applying that force downward if you apply 275 N upward force and a friend helping you applies 275 N upward force what is the net force applied?
Asked in Science, Physics, Isaac Newton
If A box weighs 35 N with gravity applying that force downward and you apply 39 N upward force to pick it up what is the net force applied?
The net force applied is 4N upward ( 39-35); that means the box is accelerating upward as you lift it. ...
Asked in Gravity
How is gravity and friction different?
Gravity and friction is different because gravity is the force of something thats going downward and friction is the force that is being pushed if touching the ground. For example, if you was to go skating the friction is the force that you applied between the skates and the ground. ...

Explain how newtons 1st law applies to the clean and jerk?
well if they think about it the square root of turkey is 57 so this proves that gravity is 67m/s in a downward direction ...

What can be defined as a root's downward growth as a response to gravity?
A root's downward growth as a response to gravity is called positive gravitropism or positive geotropism. ...
Asked in Gravity
How is the force of earth's gravity overcome when an object is launched?
By applying an upward force on the object that is greater than the downward force of Earth's gravity acting on it. Somewhat the same thing that you do with your leg muscles when you walk upstairs, or go in for a jump shot. ...
Asked in Physics, Kinematics, Newtons Laws of Motion
Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Acceleration only depends on the direction of the applied force and is independent of the velocity of the object, so gravity is always pointing down. ...

What type of force is used in downhill mountain biking?
Gravity does the most of it, but then there's the effort applied by the rider as well. A combination of gravatational force and also downward weight force by the rider. ...
Asked in Science
What is downward force?
The most usual downward force is the force of gravity; the weight of an object exerts force in a downward direction. There are also other forces which can be exerted in that direction. If you wanted to, you could fire a gun in a downward direction, in which case the explosive force of the gun is added to the force of gravity. ...
Asked in Physics
Why does a projectile move upwards when thrown upwards even though a force of gravity acts downwards on it?
In the act of "throwing", the thrower imparts an upward velocity to the object, by temporarily applying an upward force to it that's greater than the downward force of gravity. During that brief period, the sum of the forces on the object is directed upward, so it accelerates in that direction. After the throwing ends, however, the only force on the object is the force of gravity, directed downward, so its acceleration is downward. That means that the upward velocity becomes smaller and smaller, until it's zero...
