What is the acceleration of a. 1.4 kg object if the gravitational force pulls downward on orbit the air resistance pushes up on it with a force of 2.5N?
The net force acting on the object is the difference between the gravitational force pulling downward and the air resistance pushing upward. Calculate the net force: 2.5N (upward) - mg (gravitational force). Then, use Newton's second law, F = ma, to find the acceleration a = net force / mass.
How big is the upward force compared to the downward force?
Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.
When you are standing on the ground how much upward force is exerted on you by the earth?
When standing on the ground, the Earth exerts a force equal to your weight in the downward direction (gravitational force) and you exert an equal force in the upward direction on the Earth (reaction force) as per Newton's Third Law of Motion.
When a body is immersed in a liquid name the two forces acting on it and state their direction of action?
The two forces acting on a body immersed in a liquid are buoyant force (upward direction) and gravitational force (downward direction). Buoyant force acts in the opposite direction to the gravitational force.
What force acts against the gravitational force that is in the upward direction?
The force that acts against the gravitational force in the upward direction is the normal force. The normal force is exerted by a surface in contact with an object and is perpendicular to that surface. It prevents the object from falling through the surface due to gravity and is equal in magnitude but opposite in direction to the gravitational force acting on the object.
What is the property of water to move upward against the gravitational force?
capillary
Why flame of candle will go upward?
gravitational force con't effect on gasses..
Are acting on the pen?
The Forces acting on the pen are first the downward force called gravitational force and the upward force is the tension force.

What is buoyancy force?
Buoyancy is an upward acting force. It is caused by fluid preassure which opposes an objects weight ( their gravitational pull downwards ).
How big is the upward force compared to the downward force?
Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.
Is gravitational force equal to the weight of the fluid displaced by an object?
No. Gravitational force is directed DOWNward. The weight of the displaced fluid is another force, directed UPward. If they happen to be equal, then the net force on the object is zero and it floats. But they don't have to be equal.
Buoyancy is a force that always acts in an?
Buoyancy always acts in the direction opposite to the direction of the gravitational force. We normally consider this direction as 'upward'.
Why does buoyant force act upward?
The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.
When you are standing on the ground how much upward force is exerted on you by the earth?
When standing on the ground, the Earth exerts a force equal to your weight in the downward direction (gravitational force) and you exert an equal force in the upward direction on the Earth (reaction force) as per Newton's Third Law of Motion.
