force down f=ma
air restance force is dependant on velocity and aerodynamics
say 100kg falling , terminal velocity = 70m/s
f=ma = 100 *10 = 1000n
at terminal velocity forces equal
air resistance 1000n = v^2* resistance figure for this body (r)
r = 1000/v^2
r = 1000/4900
r = 0.204 this figure can be used to calculate air resistance at different speeds
What else can I help you with?
Is a net force being applied to a object when its moving downward with a constant acceleration of 9.80?
Yes, of course. If it is accelerating, it follows directly from Newton's Second Law that there is a net force acting on the object.
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.
What is the sum of all forces acting on an object?
The sum of all forces acting on an object is known as the net force. This net force determines the object's acceleration according to Newton's second law of motion, F = ma, where F is the net force, m is the object's mass, and a is its acceleration.
What Combination of all of the force acting on an object?
The net force acting on an object is the combination of all individual forces acting on it. It is the vector sum of all forces, taking into account their magnitudes and directions. The net force determines the acceleration of the object according to Newton's second law of motion.
When an object reaches terminal velocity what is the net force acting on the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
What if the upward force of an object is more than the downward force of an object?
If the upward force acting on an object is greater than the downward force (its weight or force of gravity), the object will experience a net upward force causing it to accelerate in the upward direction. This could lead to the object moving upwards, overcoming the force of gravity pulling it downward.
What is the net force that acts on a 10- freely falling object?
Ten newtons downward, by definition.
Is a net force being applied to a object when its moving downward with a constant acceleration of 9.80?
Yes, of course. If it is accelerating, it follows directly from Newton's Second Law that there is a net force acting on the object.
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.
What is net force acting on a falling object when it reaches terminal velocity?
When an object reaches terminal velocity, the net force acting on it is zero. This occurs because the gravitational force pulling the object downward is balanced by the air resistance pushing against the object in the opposite direction, causing the object to fall at a constant velocity.
What do you get when you subtract the forces of air resistance from the forces of gravity?
Terminal Velocity
What happen when the downward pull of gravity on an object is equal to the upward force of water?
When the downward pull of gravity on an object is equal to the upward force of water (buoyancy), the object will float at a certain level in the water. This is known as the object being in equilibrium, where the forces are balanced and there is no net force acting on the object.
What is the net force that acts on a 1-kg freely falling object?
The net force acting on a 1-kg freely falling object is equal to its weight, which is the force of gravity pulling it downward. This force is approximately 9.8 newtons (N) on Earth.
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.
What is the upward force on a moving object with a lift at a rate of 17m per s?
If the object is moving at a constant speed, the net force on it is 0. So the upward force would have to be equal to the downward force (namely the weight of the object).
Why does a egg gain speed on the way down?
Any falling object, or object that rolls downwards, can gain speed. This can easily be explained by Newton's Third Law: acceleration = force / mass. Force refers to the net force. So, as long as there is a net force downward, the object will continue accelerating. Only when the upwards forces (basically, friction) become as strong as the downward force of gravity will the object start accelerating. In that case, the object is said to have achieved "terminal velocity".
Can something move 1 direction and have net force in the other direction?
Yes. What the net force does is affect acceleration. For example, when you throw an object up, once it is in the air the net force on it is downward - so of course it accelerates downward. But due to the fact that it was initially moving upward, it will continue moving upward - at least for a while.
