How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
What quantities are needed to calculate an object's resistance?
Voltage, current, or power. You need two out of the three.
What is the rate at which an object is moving at a given instant called?
speed if no direction is needed velocity if direction is needed
What do you call the the quantity that describes a moving object using magnitudes only?
The quantities that describes about only magnitude is called SCALAR quantity
What changes when you change the mass of a moving object?
Quantities which depend on the mass of an object are its momentum, and kinetic energy.Both change if the mass changes. In addition, if the object's volume doesn't change,then its density also changes.
What is needed when describing motion?
object,place,force,direction,speed and acceleration

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.
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.

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.

How much force is needed to keep a 2kg object moving?
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.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
An unbalanced force
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.
