what is the property of an object due to its mass by which it resists any change in its position unless overcome by force ?

The built in flash in a compact camera is usally capable of giving correct exsposure for distance up to how many meters?

Aproton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
