Is a force needed to keep a moving spacecraft moving in a straight line?
It depends where the space craft is. If it is in deep space far away from any large mass (like a planet, star, etc) then the answer is no. If it is close to a mass then the answer is yes. An equal and opposite force is required to balance the gravitational force to keep it moving in a straight line.
Forces acting on an object that is not moving are described as this?
It can be said that the net force applied on the object is zero or that the object is in translational equilibrium. Keep in mind that these terms can also be applied if the object is moving at a constant velocity.
The centripetal force of a body having mass m and rotating at a linear speed of v in a circle of radius r is given by mvr mvr mv2r mvr2?
none of the above Force centripetal = (mass * velocity^2) ÷ radius More mass , more force needed to keep object in the circle Object going faster, more force needed to keep object in the circle Larger radius, less force needed to keep object in the circle That is why mass and velocity are in the numerator ( multipliers) and Radius is in the denominator ( divider)
How much force does it take to keep an object moving in a straight line at a constant speed?
To keep an object moving in a straight line at a constant speed, you need to apply a force equal to the force of friction or any other resistive forces acting on the object. This force is called the net external force and is equal in magnitude but opposite in direction to the sum of all resistive forces.
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
How much force is needed to move an object?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What force is needed to keep an object in circular motion?
The centripetal force is the force needed to keep an object in circular motion. This force is directed towards the center of the circular path and is responsible for continuously changing the direction of the object's velocity. It depends on the mass of the object, the speed at which it is moving, and the radius of the circular path.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
Why is less force needed to keep an object moving than to start the object in motion?
1). Because maintaining an object in motion requires no force, but causing a non-moving object to move involves acceleration which does require force. 2). Because kinetic friction is generally less than static friction.
No force is necessary to?
to keep an object moving the way it is already moving .
The inward force needed to keep an object moving in a circle?
The force that keeps objects moving in a circle is known as the centripetal force, which acts towards the center. The velocity of the object moving in a circle will be tangential to the circle.
Why does it take more force to get an object moving than to keep it moving?
It takes more force to get an object moving because you need to overcome its initial inertia, which is the resistance of the object to changes in its motion. Once the object is moving, it requires less force to keep it in motion because there is less resistance once it has overcome the inertia.
Is it true that to keep an object moving a force must be apllied?
Yes, according to Newton's first law of motion, an object will remain in its state of motion (either at rest or moving at a constant velocity) unless acted upon by an external force. In order to keep an object moving, a force must be continuously applied to overcome any friction or resistance that might slow it down.
What is the relationship between centripetal force and speed?
The centripetal force required to keep an object moving in a circular path increases as the speed of the object increases. This is because the force needed to counteract the tendency of the object to move in a straight line (due to inertia) is directly proportional to the square of the object's speed.
