One. Only the bullet's weight. In this case, the bullet would not decelerate and will keep moving at muzzle velocity until it hits the ground.
It has gravity pulling it down, inertia pushing it forward, the spin of the bullet causing it to curve VERY slightly, and air resistance slowing it down.
no. a force acting perpendicularly on a body cannot cancel a force which is acting horizontally on the same body.!!!!
Because there's no horizontal force acting on it that would change its horizontal component of velocity. (In practice, that's not completely true, since the frictional 'force' of air resistance acts in any direction. But outside of air resistance, there's nothing else acting horizontally on the projectile.)
The ball would continue straight without any gravitational forces acting on it, and without air resistance. If you consider air resistance, then the spin of the ball may give it a curved path, and eventually the ball would stop traveling as the air resistance slows down the ball.
name the two forces acting on the rocket immediately after leaving the launching pad
The forces acting on the bike is gravity, air resistance and friction.
If your boyfriend is ignoring you, then ignore him back..show him that you don't care, and you can have fun without him..guys hate that..once you start acting like you don't care, then he will realize he will loose you if he don't start acting right...
"Free fall" means that gravity is the only force acting on a body.
Usually gravity AND air resistance.
Gravity and air resistance.
There is the apple's weight (mass * gravity) but there is also the air resistance acting against the object's weight.
The gravitational pull on the falling man and the wind resistance acting against the fall.
