What is an example of an object with a momentum of zero?
An object at rest has zero momentum. For example, a stationary rock on the ground has zero momentum because both its mass and velocity are zero.
The energy transformation that occurs as a rock falls off a cliff.?
The potential energy of the rock is transformed into kinetic energy as it falls due to gravity. As the rock falls, some of its kinetic energy is also converted into heat and sound energy upon impact with the ground or other objects.
When a rock is held above the ground you say it has some potential energy When you let it go it falls and you say the potential energy is converted to kinetic energy Finally the rock hits the ground W?
Yes, when the rock is held above the ground, it possesses potential energy due to its position. As it falls, this potential energy is converted to kinetic energy, which is the energy of motion. When the rock hits the ground, this kinetic energy is transferred into other forms of energy, such as sound and heat.
What energy is caused when a rock falls off a cliff?
The energy caused when a rock falls off a cliff is primarily gravitational potential energy being converted to kinetic energy as the rock accelerates towards the ground. This kinetic energy increases as the rock falls, and upon impact, some of it is converted into sound and heat energy due to the collision.
A 81 kg astronaut floating in space throws a 5.9 kg rock at 5.3 meters per sec. How fast does the astronaut move backward?
He deposits (5.9 x 5.3) kg-m/sec of momentum to the rock, in that direction ---> . Since momentum is conserved, he himself must acquire the same amount of momentum in this direction <---. (His mass) times (his speed) = (5.9 x 5.3) His speed = (5.9 x 5.3) / (his mass) = (5.9 x 5.3 / 81) = 0.386 m/s (rounded)
What increases as a rock falls on the ground?
As a rock falls on the ground, its kinetic energy increases due to its increasing speed and momentum. The potential energy of the rock decreases as it loses height. The impact force between the rock and the ground increases as the rock accelerates towards the ground.
What increases as a rock falls to the ground?
As a rock falls to the ground, its kinetic energy increases due to its increasing velocity towards the Earth's surface. The rock's potential energy decreases as it loses height and moves closer to the ground. Additionally, the rock's acceleration due to gravity increases as it falls, leading to an increase in its overall speed and momentum.
How does the total energy change when when a falling rock hits the ground?
when the rock falls it gain kinetic energy when it falls.
What is an example of an object with a momentum of zero?
An object at rest has zero momentum. For example, a stationary rock on the ground has zero momentum because both its mass and velocity are zero.
When a rock falls from outerspace onto the ground it is called?
Meteorite.
Does the density of a rock increase as a rock falls to the ground?
No, the density of a rock does not increase as it falls to the ground. Density is a measure of mass per unit volume, and while the rock may experience changes in pressure as it falls, its mass and volume remain constant. Therefore, the density remains unchanged regardless of its motion.
When a rock falls from outer space a the way to the ground it is called a?
A meteorite.
When a rock falls outer space all the way to the ground it is a called a?
A meteorite.
When a rock falls from outer space all the way to the ground, its called a?
A meteorite.
How do waterfalls destroy themselves?
Waterfalls destroy themselves through having a current that destroys the rock supporting the cliff through which the water falls. eg: ====" rock " rock " rock " rock @====== water==== where the @ sign is located there is water turbulance which errodes the base rock of the falls, through this action the stability for the upper rock is taken away and it eventually falls. This can cause a loss of height of the falls, recession of the falls, or change it into a gorge.
The energy transformation that occurs as a rock falls off a cliff.?
The potential energy of the rock is transformed into kinetic energy as it falls due to gravity. As the rock falls, some of its kinetic energy is also converted into heat and sound energy upon impact with the ground or other objects.
What causes a metamorphic rock to change into an igneous rock?
it falls in magma and melts to molten rock and when it pops out of the volcano and hardens its a igneous rock!
