because there if speed is constant than ball never come back to earth hence speed of ball is not constant
If the applied force is constant, the acceleration will also be constant. To know the actual amount of acceleration, you divide the force by the mass.
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.
No. Acceleration is proportional to the applied force.
Because of the force of gravity
50 N upward
50 N upward
Objects fall to the ground because of the force of gravity.
4 N upward
4 N upward
The kinetic energy will be decrease because when the body thrown in upward direction the gravitation force will be act in opposite direction which reduce the velocity.so the velocity will decrease.
If the object is moving at a constant speed, the net force on it is 0. So the upward force would have to be equal to the downward force (namely the weight of the object).
If there is no force against motion,applied force is zero. If there is force against motion,applied force is equal and opposite to that force.
