Are any the forces acting on the freezer balanced?
are any the forces acting on the freezer balanced
If balanced forces are acting on an object it will seem as if a net force is acting on the object?
If the forces are balanced this means that there is no net force acting
What are 4 forces acting in an airplane during flight?
Forces acting on an aircraft in flight are:gravityliftdrag
Is it possible for an object to not be in motion and still have forces acting on it?
Yes, the object can have equal forces acting in opposite directions: 5N ->[]<- 5N The object will have forces acting upon it, but will not move.
What is a state in which all forces acting on an object are in balance?
Equilibrium is a state in which all forces acting on an object are in balance.

What forces are acting when you are riding and then thrown from your bike?
The forces acting on the bike is gravity, air resistance and friction.
What are the similarities between balanced and unbalanced forces?
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
How an object can have forces acting on it but not be accelerating?
Yes - if the sum of the forces is zero.Yes - if the sum of the forces is zero.Yes - if the sum of the forces is zero.Yes - if the sum of the forces is zero.
Are the force acting on the pen?
Yes there are forces acting on a pen.
What is a state in which all forces acting on an object are in balance?
Equilibrium is a state in which all forces acting on an object are in balance.
How many forces acting are on a rocket?
There are four forces acting upon a rocket these are: Thrust, Gravity, Drag and Lift.
Balanced forces acting on an object do not change the object's what?
Balanced forces acting on an object do not change the object's position.
What are the forces on a kite?
An excellent way for students to gain a feel for aerodynamic forces is to fly a kite. Kites can fly because of the forces acting on the parts of the kite. Though kites come in many shapes and sizes, the forces which act on a kite are the same for all kites and are shown on this slide. You can compare these forces to the forces acting on an airliner in flight and you will find that, with the tension substituting for thrust, they are exactly the same. The similarity in forces allowed the Wright brothersto test their theories of flight by flying their aircraft as kites from 1900 to 1902.This page shows a free body diagram of the kite. In a free body diagram, we draw a single object and all of the forces which act on that object. Forces are vectors having both a magnitude and a direction, so we draw each force as an arrow with the length proportional to the magnitude and the head of the arrow pointing in the direction of the force. An important property of vectors is that they can be broken down into perpendicular components, and we can develop scalar equations in each component direction.On the page, there are three principle forces acting on the kite; the weight, the tension in the line, and the aerodynamic force. The weight W always acts from the center of gravity toward the center of the earth. The aerodynamic force is usually broken into two components (shown in blue); the lift L, which acts perpendicular to the wind, and the drag D, which acts in the direction of the wind. The aerodynamic force acts through the center of pressure. Near the ground, the wind may swirl and gust because of turbulence in the earth's boundary layer. But away from the ground, the wind is fairly constant and parallel to the surface of the earth. In this case, the lift is directly opposed to the weight of the kite, as shown in the figure. The tension in the line acts through the bridle point where the line is attached to the kite bridle. We break the tension into two components, the vertical pull Pv, and the horizontal pull Ph.When the kite is in stable flight the forces remain constant and there is no net external force acting on the kite, from Newton's first law of motion. In the vertical direction, the sum of the forces is zero. So, the vertical pull plus the weight minus the lift is equal to zero.Pv + W - L = 0In the horizontal direction, the sum of the horizontal pull and the drag must also equal zero.Ph - D = 0With some knowledge of the kite geometry and the velocity of the wind, we can determine the value of the lift and drag. And with knowledge of the kite geometry and the materials used to make the kite we can determine the weight. We can then solve the two equations given above for the horizontal and vertical components of the tension in the line.Near the bridle point, the line is inclined at an angle called the bridle angle b. The magnitude of this angle is related to the relative magnitude of the components of the tension.tan b = Pv / Phwhere tan is the trigonometric tangent function. Knowing the bridle angle, the length of line, and the weight per length of line, you can predict the height at which the kite flies. You can use the KiteModeler program to solve all the equations shown on this slide.The relative strength of the forces determines the motion of the kite as described by Newton's laws of motion. If a gust of wind strikes the kite, the lift and drag increase. The kite then moves vertically because the lift now exceeds the weight and the vertical pull, and the tension force increases because of increased drag. Eventually a new balance point is established and the kite achieves a different stable condition. Because of the change in relative strength of the aerodynamic and weight forces, the kite also rotates about the bridle point to balance the torques.
