When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
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 the upwars force acting on an object?
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
If an object is thrown up in the air how does its gravitational potential energy change?
If the objects only source of thrust is the hand, it does not accelerate, it decelerates due to friction and resistance.Answer:The object accelerates as it is propelled upward and is still in contact with the hand. This cannot be determined without data on the velocity at which it leaves the hand. The formula used is:a=vf - vi / twhere a is accelerationvf is final velocityvi is initial velocityand t is time takenOnce free it accelerates negatively at the gravitational constant "-g" (-32 ft/sec2). Upon reaching the apex of its trajectory it accelerates downward at g=32 ft/sec2 until it strikes the ground. If the object is thrown in an atmosphere the apex of the trajectory is reduced by drag and the downward velocity reaches a maximum at the object's terminal velocity.
How will the upward force of air resistance compare to the downwward pull of gravity?
Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction... When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.
Why do objects fall to the ground when thrown upward?
Objects fall back to the ground when thrown upward due to the force of gravity acting upon them. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downwards. When an object is thrown up, it loses its upward velocity and gravity then pulls it back towards the ground.
How the velocity of the vertically thrown ball varies with time?
The ball is affected by the force of the earth's gravity.
Does earths exerts an unbalanced force in a ball thrown into the air?
Yes, Earth exerts a downward force on the ball due to gravity, causing it to fall back to the ground. This creates an unbalanced force on the ball when it is thrown upward, with gravity acting to pull it back down.
When body is thrown in upward direction then what will happen about kinetic energy?
The kinetic energy will be decrease because when the body thrown in upward direction the gravitation force will be act in opposite direction which reduce the velocity.so the velocity will decrease.
When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
Why does the velocity decrease when a stone is thrown upwards?
The velocity decreases as the stone moves upward due to the force of gravity acting in the opposite direction of the motion. Gravity slows down the stone's speed, eventually bringing it to a stop at the highest point before it starts to fall back down.
Are there any balanced forces acting on the freezer if so what are they?
Yes, if a freezer is at a constant velocity or stationary, there are balanced forces acting on it. Typically, these forces include the gravitational force acting downward and the normal force acting upward from the surface on which the freezer rests.
What is the upward force that acts on an object that is falling through the air?
The upward force acting on an object falling through the air is called air resistance or drag. This force opposes the motion of the object and increases as the object's speed increases. It ultimately results in a terminal velocity when the upward force equals the downward force of gravity.
A ball is thrown horizontally from a window on the second floor of a building What is the vertical component of its initial velocity?
The vertical component of the initial velocity of the ball thrown horizontally from a window is zero. The ball's initial velocity in the vertical direction is influenced only by the force of gravity, not the horizontal throw.
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 the upward force acting when a vehicle is moving?
upthrust
What force is not acting upon a ball that is thrown in the air?
The force of friction is not acting upon a ball that is thrown in the air. Friction is a force that opposes motion, but when a ball is thrown in the air, there is no surface contact for friction to act upon.
