A ball is thrown upward and caught when it comes back down In the presence of air resistance the speed with which it is caught is?
less than the speed it had when thrown upward.
When a body is thrown upwardhow many forces act on it?
when abody is thrown upward,how many forces act on it?what is the role of the force with which the body has been thrown upward? After a body is thrown upwards, you have gravity pulling it down and friction slowing it.
What forces govern thrown objects?
Momentum- a moving object tends to keep moving. Friction- pushing air out of the way slows it down. Gravity- pulls it down
A ball is thrown upward What can be said about the system?
The ball can be considered a closed system.
What happens to something that is inside a tornado?
Objects inside of a tornado may be carried or thrown some distance, and often not in one pieces. Objects that are anchored down to too heavy to lift may be damage or destroyed.
Why things thrown upward goes back to the ground?
Because they are in Earth's gravity well. They would have to move much faster than you can throw them to keep going up instead of falling back down.
What describes unequal forces acting on a object-results in a change in the objects motion in the direction of the larger force?
Picking up a glass of beer from the table. Force of gravity . . . down. Force of arm muscle . . . upward. Forces are unequal. Upward force is greater than downward force. Glass accelerates upward, toward mouth.
What are examples of both projectile motion and two dimensional motion?
There is insufficient information in the question to properly answer it. You did not provide the list of "the following objects". Please restate the question.By the way; all objects exhibit two-dimensional motion. Kepler's Laws of Planetary Motion and Newton's Law of Motion come down to providing that an object in orbit around another object will describe a conic section, i.e. plane geometry, around the other object. Don't know if that's what your talking about, but I thought I would toss that into the mix. Of course, a third object would upset that pretty little conic section, wouldn't it? But now we are getting into relativity and we are way off topic...
A rock is thrown upward at an angle of 50 degree with respect to the horizontal As it risesm its horizontal component of velocity?
If you ignore the effect of the air grabbing at it and only figure in gravity, then the horizontal component of velocity is constant, from the time the stone leaves your hand until the time it hits the ground. Makes no difference whether you toss it up, down, horizontal, or on a slant. Also makes no difference whether it's a cannonball, a stone, or a bullet.
How is gravity different for objects that freely fall down and those thrown upwards?
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
Does gravity stop you from jumping?
Gravity works equally on every particle in a "standard" object which is why all objects fall at the same rate. Yes, you can exert an upward force greater than 1G when jumping, but even during the jump, gravity is already working on decelerating your upward speed and pulling you back down.
Why do objects falling through the air start to slow down?
There is something called "air resistance" or "friction".
