Can an object with a constant acceleration reverse its direction of travel?
Of course. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Is gravity important to the water cycle?
G ravity may move the water downward through spaces in rock or soil, where the water becomes groundwater
What do you think may happen to leading edge of plate a as it continues to downward?
As the leading edge in forced down it is heated up and becomes part of the molten magma below.
What is downwelling?
The Coriolis Effect causes water to be pushed onto shore and when the water on the surface of the sea becomes denser than the water beneath it, it sinks.
What forces have to be balanced for terminal velocity to be reached by an object?
For an object in freefall, terminal velocity is reached when the drag force becomes equal and opposite to the force of gravity. This creates a net force of 0, resulting in no further acceleration.
Describe how the velocity and acceleration of an object change as it fell from tall building?
The magnitude of the velocity will increase. The velocity will be downward - and since it increases, the acceleration will be downward. The acceleration doesn't change (it will remain constant at about 9.8 m/sec2), unless air resistance becomes significant.
Why do falling objects reach a terminal velocity?
When the force of friction due to air resistance at that speed becomes equal to the object's weight. At that point, the sum of the vertical forces on the object is zero, so it no longer accelerates.
What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
What is weightlessness?
Weightlessness is a condition when the magnitude of weight of respective mass becomes zero.
Is it possible for an object not to be in full motion and still have forces acting on it?
Yes hanging load. Its weight ie force due to gravity is acting downward. And the tension the rope is acting upward. Both the forces are acting on the load but as they are equal in magnitude and opposite in direction the resultant becomes zero.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
What has the least amount of resistance a semi conductor insulator resistor or a conductor?
Traditionally, a conductor has the least resistance of the three, followed by the semiconductor and finally the resistor.
Why does resistance decrease as the NTC Resitor becomes warmer?
cause it does
When a raindrop falls from clouds then as the gravitional force is counterbalanced by the viscous force of the air so it should not fall. But how it is falling?
You are wrong at this point. When the raindrop starts to fall, its weight is the only force acting on it. When it starts to accelerate due to this force, the drag force, or air resistance, becomes significant. The magnitude of the drag force will increase as it continues to accelerate, until it equals the magnitude of the weight. At this point, net force will be zero. However, according to Newton's first law, the object should continue to drop, but with constant speed. You are wrong in the belief that the magnitude of the air resistance is equal to the weight since the beginning. This is not the case. Instead, the magnitude of air resistance was zero when the raindrop starts to fall, but increases as it accelerates until it equals the weight. At this point, the drag force will no longer increase as the rain drop does not accelerate anymore.
Each time the magnitude of an earthquake increases by one unit the measured ground motion becomes more larger?
it becomes 1 time larger
From the surface downward how does soil vary with depth?
The soil becomes rockier, less fertile, and more like the parent
When a current passes through a resistance what is the electric energy that is lost?
Becomes heat.
