What force keeps an object in free space going a constant speed?
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
Why force changes the speed of an object?
Force = Mass * Acceleration or Acceleration = Force / MassThe Mass is the mass of the object and the Acceleration is the change of speed of the object due to the Force.
Which a force changes the speed of an object?
Any force will do. The only condition is that the TOTAL (or NET) force acting on an object is non-zero.
Why is KE equal to half mass velocity squared?
You can derive it from accelerating an object to a certain speed. Assume constant acceleration (and therefore constant force), and calculate how much work (force x distance) you need to get the object to a specific speed.
How can speed of an object change?
The speed of an object only changes if it is acted upon by another force (Newton's first law).
How do you calculate forse on a speed time graph?
If you only have the speed/time graph, you can't calculate force out of it. You could if you also knew the mass of the object that's speeding along, but not with the speed alone.
How do you calculate HP need to keep constant speed?
It is equal to the retarding force due to friction.
Why can you only calculate a stone's average speed during its fall?
That is just not true! If you can calculate its average speed you should be able to calculate its speed at any point in time during its flight, including its final velocity.
What force keeps an object in free space going a constant speed?
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
Why gravitational force increases when you fly with supersonic speed?
Gravitational force depends only on an object's mass and its distance from the center of the earth. Its speed has no effect on the gravitational force.
How much centripetal force is needed to keep a 0.24 kg ball on a 1.72 m string moving in a circular path with a speed of 3.0 ms?
Calculate the centripetal acceleration, using the formula:acceleration = speed squared / radius Once you have this acceleration, you can use Newton's Second Law to calculate the force.
How many hours does it take to drive 574 miles?
That depends on the speed. Divide the distance by the speed to calculate this.That depends on the speed. Divide the distance by the speed to calculate this.That depends on the speed. Divide the distance by the speed to calculate this.That depends on the speed. Divide the distance by the speed to calculate this.
Why force changes the speed of an object?
Force = Mass * Acceleration or Acceleration = Force / MassThe Mass is the mass of the object and the Acceleration is the change of speed of the object due to the Force.
What is the centripetal force on a 4 kg moving at meter-SEC around a curve with a radius of 4 meters?
First, calculate the centripetal acceleration, as speed squared divided by radius.Then you can use Newton's Second Law to calculate the corresponding force.
Which a force changes the speed of an object?
Any force will do. The only condition is that the TOTAL (or NET) force acting on an object is non-zero.
Why is KE equal to half mass velocity squared?
You can derive it from accelerating an object to a certain speed. Assume constant acceleration (and therefore constant force), and calculate how much work (force x distance) you need to get the object to a specific speed.
If the formula to calculate work is distance divided by time how do you apply the formula?
You would have a very tough time, because that isn't the formula to calculate work. (distance) divided by (time) is the formula to calculate speed. The formula to calculate work is: (force) multiplied by (distance).
