Explain the energy conversions that occur as a pendulum swings and how does this demonstrate conservation of energy?
When the pendulum is at it's highest point in it's path of flight, the pendulum is not moving, and has purely potential energy. When the pendulum reaches the lowest point in it's flight, that potential energy is converted into kinetic. The total amount of energy has not changed though.
Let's make up numbers to prove how this is true. Say we have a ball on the end of the pendulum that weighs 10kg. At it's max height, the ball reaches 5 meters above it's starting point. Since potential energy (PE) = mass (m) x gravity (g) x height (h), our PE = (5kg)(10m/s^2)(5m) = 250 Joules. As I mentioned earlier, total potential energy will equal the total kinetic energy (KE). When the ball reaches it's lowest point (where it's velocity is the highest), we can use our PE energy from the first equation to determine how fast the ball is moving at the bottom of the swing. KE = (1/2) x mass (m) x velocity (v) squared. Since KE also equals PE, we have 250 = (1/2)(5)(v^2) --> 100 = v^2. Therefore the veolcity equals 10 meters per second.

How is the conservation of momentum important to astronomy?
There are several conservation laws in physics, and many of them tell an astronomer what is, and what isn't, possible. This can help explain how certain things happen, or even predict what will happen. Among the laws of conservation that are relevant in astronomy are: conservation of mass; conservation of energy; conservation of momentum; conservation of rotational momentum; conservation of charge.
Explain why when you jump from a boat the boat moves back as you move forward?
This is an example of Newton's Third Law. It can also be explained - equivalently - via conservation of momentum.
Explain the law of energy conservation?
According to the law of conservation of energy,energy can only converted from one form to another; it can be neither be created nor destroyed total energy before and after transformation remains same
Explain why an object cannot keep accelerating?
what your talking about is terminal velocity, which is when the downward force of gravity (Fg)equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero
How does the atomic theory of matter explain the law of conservation of mass and law of constant composition?
Each atom of a particular element has a constant (average) weight, and in chemical reactions, the numbers and types of atoms in the reactants must be the same as the numbers and types of atoms in the products. This explains the law of the conservation of mass. Each molecule of a compound or polyatomic element is composed of a fixed number of one or more particular kinds of atoms; this explains the law of constant composition.
How can we explain the concept of conservation of energy to kids in a fun and engaging way?
One way to explain the concept of conservation of energy to kids is by using a fun and engaging activity. For example, you can demonstrate how energy is transferred from one object to another by using a simple pendulum or a bouncing ball. You can also show how energy can change from one form to another, such as from potential energy to kinetic energy. By making the concept of conservation of energy hands-on and interactive, kids can better understand and remember the idea that energy cannot be created or destroyed, only transferred or transformed.
Is the potential energy of the pendulum changing at position E explain?
At position E, the potential energy of the pendulum is at its maximum. As the pendulum swings, the potential energy is converted into kinetic energy, reaching a minimum at the lowest point of the swing. The potential energy is constantly changing as the pendulum moves due to the force of gravity acting on it.

Which letters represent the positions of maximum potential energy of the pendulum explain?
The positions of maximum potential energy in a pendulum are at the highest points of its swing, where the pendulum momentarily stops before changing direction. This corresponds to the top-most points of the swing, which are generally labeled as positions A and C in diagrams.
What is difference between remonstrate and demonstrate?
Remonstrate means to plead in protest: "Please, please don't do that!" While demonstrate means to explain: "Let me show you how to do that."

What will happens to the time period of simple pendulum if bob of the pendulum is completely immersed in water Explain?
Essentially , a simple pendulum is ignorant of air resistance, its more a tool to calculate gravitational acceleration, immersing it in liquid would introduce a drag force and bouyancy on the bob which alters the net force on the bob (essentially reducing the gravity)
