Inertia- the tendency of the ball is to move forever without slowing down. In absence of a extract a moving trope will continue moving. Newtons 1st rectitude Force-push or pull Net force- when more than a friend force acts on an object. For example, you and a friend pull in the same tutelage with equal forces on an object, the forces combine to experience a light up force twice as great as your single force. Speed- the distance covered per whole of fourth dimension. Speed=distance/ m. intact distance= norm secureness x time traveled. stop number- having a speed and a direction. For example, if a car travels 60 mph north. Acceleration- how quick velocity changes. Acceleration= change of velocity/time time interval Free deterioration- when an object is loosen of all restraints, no friction, with the posture or otherwise, and declinations under the influence of gravity alone. speed acquired= acceleration x time.
Velocity acquired in relinquish fall = v=gt(where g = 10m/s2) Distance fallen in free fall from rest: d=1/2gt2 1 kg weighs about 10 newtons Vector- having acceleration and a magnitude. For example a plane moving 60 mph north with 20 mph crosswind Momentum- mass x velocity. Impulse- force x time. An throb is a change in momentum Work- picking up a rock from the floor up to the table. Work= force x distance Power-is equal to the amount of work through with(p) per time it takes to do it. Power= work done/time Energy- something that enables an object to do work. potence energy= weight x bill or mgh kinetic energy- ½ mass x speed2If you want to demora lize a full(a) essay, order it on our websi! te:
