3 forces gravity drag lift
describe the size and direction of the frictional forces when a car stops on a falt road?
One pair of forces is your hand pushing against the wind, and the wind pushing back against your hand.Another pair of forces is gravity from Earth pulling your hand down, and your hand pulling up against Earth; but this doesn't depend on the fact that the car is moving.
see it is given in the nstse book you are saying that how mad
It slows down or stops the object because of the acting force, pulling it back. Thanks, GeekyScienceGirl123 :]

During the time, you're pushing it, the forces are unbalanced. Once you stop, they are balanced. Unbalanced forces result in a change in motion, even if it is slowing it to a stop. Balanced forces produce no change.
The keel is important because it forces the boat to move forwards when the force of the wind on the sails might also be pushing the boat sideways. The keel stops the boat simply going directly downwind.
It muffles (stops) the sound because the string stops moving.
They don't. If there are no external forces acting on a moving object, then the objectcontinues moving in a straight line with constant speed. Whenever an object slows down,it must be the effect of an external force acting on it.

When it stops it stops. Inertia will stop it from moving unless there is some force acting on it.
The Earth's gravity stops the object from floating when at rest.
Inertia is the resistance to change of an object in motion. In other words, an object at rest wants to stay at rest, and an object in motion wants to stay in motion. this is why it might take a person's whole body strength to start pushing a car down the road from a dead stop, but once it is in motion, it may only take one hand to keep it moving. Once you stop pushing the car, it slows and eventually stops because the frictional forces acting against the car's motion are greater than those keeping it moving.
It stops all the air comin in ur mouth
its their teeth!
If you hold your finger over the top of the straw it does not because the gravitational force pulling on the water towards the opening at the bottom is not great enough to overcome the vacume created on the top by your finger over the hole. Space is occupied by matter and therefore displacement of matter must be replaced by matter itself whether it be air or some other substance.
