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.

Since an object moving in uniform circular motion keeps a constant speed there is no force necessary to keep it in motion?
false
Since an object moving in uniform circular moyton keeps a constant speed there is no force necessary to keep it in motion?
False (apex)
Cases when there is displacement but no force is applied?
When an object gets displaced in the absence of force acting on it, it must have already been moving? In the past a force acted on it and now the force is no longer acting on it. Like pushing on a toy car and letting go. The car continues to roll after you let go.
Explain how friction affects the motion of an object?
Friction is speed's worst enemy. If no forces act on an object, it is stationary. If a force acts on an object, it keeps going forever until another force acts on it (such as friction!!!).
Is displacement possible without any force acting on it?
YES , it can be possible because according to law of inertia if an object is moving andexternal force on it is zero then it keeps moving with constant velocity (constant speedin a straight line).Keep that up for a while and the object accomplishes some serious displacement.
Brief meaning of the law of inertia?
A moving object keeps moving, unless you force it to stop. It keeps moving in a straight line, unless you force it to change direction. It keeps moving at a constant speed, unless you force it to speed up or slow down. A stationary object remains stationary, unless you force it to start 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 keeps an object moving in a circle. in what direction does this force act?
The Centripetal force keeps a object moving in a circle and its force and acceleration are directed toward the center of the circle
Explain how friction affects the motion of an object?
Friction is speed's worst enemy. If no forces act on an object, it is stationary. If a force acts on an object, it keeps going forever until another force acts on it (such as friction!!!).
What is the force needed to lift a 2232000kg load at constant speed?
If the object is moving at constant speed, then the net force on it is zero.In order to have zero net force in the vertical direction, the lifting force is equal tothe gravitational force.The gravitational force is the object's weight. With a mass of 2,232,000 kg,the object's weight is21,873,600 newtons (4,920,712 pounds) .A force less than that much can't lift the load. A force greater than that much accelerates itupward. Once it's rising, a force of exactly that much keeps it rising at constant speed.
Is displacement possible without any force acting on it?
YES , it can be possible because according to law of inertia if an object is moving andexternal force on it is zero then it keeps moving with constant velocity (constant speedin a straight line).Keep that up for a while and the object accomplishes some serious displacement.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
What is the force that keeps an object in an orbit?
Gravity is.
Centripetal Force is that force which we apply on the object?
Centripetal force is a force that keeps an object inwards, in the case of circular motion or similar.
