What is the net force acting if your professor's car is traveling west with a constant velocity of 55 mi-hr west on a straight highway?
If the velocity of the object is constant, then the net force on it is zero.(Incidentally, if the velocity of the car is constant and not zero, then it must be ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
What is Motion without acceleration?
Motion without acceleration is when an object is moving at a constant speed in a straight line. In this scenario, the object's velocity remains constant and there is no change in its speed or direction.
What is the net force acting on a falling object when it reaches terminal velocity?
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
A high-flying jet cruises at an altitude of 30000 feet at a constant velocity of 700 kmhr. The force of the jet engines is 40000 Newtons. How much air drag acts on the craft?
Here is a hint: you can use Newton's Second Law for this one. The airplane can only go at a "constant velocity", i.e., zero acceleration, if the net force is also zero.
An airplane is flying with a net force of zero this means the airplane is?
If an airplane is flying with a net force of zero, it indicates that the forces acting on it, such as thrust, drag, lift, and weight, are balanced. This typically means the airplane is in a state of uniform motion, either cruising at a constant altitude and speed or maintaining a steady descent or ascent. In this condition, the airplane is neither accelerating nor decelerating.
What is the net force on the model airplane?
The net force on the model airplane is the vector sum of all the forces acting on it, such as lift, weight, thrust, and drag. If the net force is zero, the airplane will remain in a state of constant velocity or at rest, according to Newton's first law of motion.
Do matter weights changes while in the airplane flying on air?
No, matter weights do not change while in an airplane flying through the air. Weight is the force of gravity acting on an object, and this force remains constant regardless of whether the object is on the ground or in the air. The sensation of weightlessness experienced in an airplane is due to the feeling of free-fall rather than a change in actual weight.
Why areal velocity is constant in central force?
In central force motion, the centripetal force acts perpendicularly to the velocity, causing the direction of the velocity to change but not its magnitude. As a result, the areal velocity (the rate at which the radius vector sweeps out area in a given amount of time) remains constant. This is a consequence of angular momentum conservation in a central force field.
How an aeroplane fly at constant velocity?
For knowing how an airplane flies at constant speed, follow this link: http://science.howstuffworks.com/transport/flight/modern/airplanes.htm I can't explain this in detail in writing but you can understand very well from this site
A feather with no net force on it maintains constant?
In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.
Suppose the force of friction on a sliding object is 10N. what is the force needed to maintain a constant velocity is?
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
If we are told that an object has a constant velocity what can we say about the force on that object?
If an object is moving with constant velocity, then the net force acting on it is zero. This means that the forces acting on the object are balanced, resulting in no acceleration and a constant velocity.
Does your weight change when you are flying in an airplaine?
Your weight does not change when you are flying in an airplane because your weight is a measure of the force of gravity acting on your mass, which remains constant. However, you may feel lighter due to the sensation of weightlessness caused by the airplane's motion and the lift generated by the wings.
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
What is the net force acting on a car cruising at a constant velocity of 70 kmh on a level road?
If the velocity is constant (no acceleration), the net force is zero.
