## FAQs

### A Person Has A Choice Of Sliding Down Three Slides, Which Are Shown Below. All Slides Start At The Same Height Above The Ground. Ignoring Friction, For Which Slide Will The Final Speed Of The Person At The Bottom Be The Highest? ›

A person has a choice of sliding down three slides, which are shown below. All slides start at the same height above the ground. Ignoring friction, for which slide will the final speed of the person at the bottom be the highest? The final speed will be the same, regardless of which slide is used.

What energy changes happen when a person goes down a slide? ›

As you go down the slide, the potential energy is converted to kinetic energy. And the difference in your potential energy and kinetic energy is lost in the form of thermal energy due to friction.

What kind of energy does a child going down a slide have? ›

At the beginning the child has gravitational potential energy at the top of the slide. When the child reaches the bottom, the child has both kinetic energy and thermal energy as some energy was converted to heat because of the friction on the slide.

What type of energy does the skater have at the lowest point on the track? ›

skater's kinetic energy is greatest at the lowest point of the track, where the skater is moving the fastest. Now observe the potential energy bar on the Bar Graph.

Can three helium nuclei fuse together forming one carbon nucleus? ›

Each helium nucleus contains four particles – two neutrons and two protons. Three of these helium nuclei combine to form one carbon nucleus with six protons and six neutrons – a total of 12 particles.

What type of friction is going down a slide? ›

Sliding friction is the force acting against two objects sliding against each other. Sliding friction is less than static friction.

Why do people have the same speed at the bottom of a slide? ›

The gravitational potential energy store decreases as they move down. So they all have the same velocity as they travelling down the same vertical height at the acceleration of free fall (because of no air resistance).

What energy is gained by a child at the top of a slide? ›

When she is at the top of the slide, the child-Earth system has 1,000 J of gravitational potential energy, using the bottom of the slide as the reference level. She gives herself a push so that she also possesses 400 J of kinetic energy at the beginning of her motion down the slide.

What type of energy does a slide use? ›

A SLIDE converts potential energy to motion energy. As you climb the steps you gain potential energy (from gravity pulling on you). As you slide downwards, the potential energy reduces, and is converted to motion energy.

Which of the following describes the energy changes that occur while a child is sliding down a roller coaster hill? ›

Each loss in height corresponds to a gain of speed as potential energy (due to height) is transformed into kinetic energy (due to speed). This transformation of mechanical energy from the form of potential to the form of kinetic and vice versa is illustrated in the animation below.

### What type of energy decreases as the skater moves down the ramp? ›

Potential Energy is the energy stored in an object because of its position. Kinetic Energy is the energy of motion. As the skateboard rolls down the ramp it loses potential energy and gains kinetic energy. The total energy of the skateboarder remains constant.

What type of energy increases as the skater moves down the ramp? ›

As the skateboarder goes down the ramp, potential energy is converted to kinetic energy. Because of friction, some of the energy in the system is converted to heat energy. Once the kinetic energy is converted to heat, the energy cannot be converted back to the potential or kinetic energy in the system.

Is skating potential or kinetic energy? ›

2 Answers. The energy comes from the ice-skater's muscles; they have to work to pull their arms in. There is no external work done on the skater - the energy is converted from the chemical potential energy stored in the skater's body to kinetic energy.

What will be produced if 3 helium nuclei fuse? ›

At temperatures of about 100,000,000 to 200,000,000 K (1 to 2 × 108 K), three helium nuclei can fuse to form carbon.

What happens when 3 helium atoms fuse? ›

In massive stars, three helium atoms fuse together, forming a carbon nucleus.

What do three 3 helium nuclei fuse to make? ›

A nuclear fusion reaction in which three helium nuclei (alpha particles) fuse to form a carbon nucleus, thereby releasing energy.

What happens to energy when you drop something? ›

You are giving the ball potential energy, specifically gravitational potential energy. Gravitational potential energy is the energy gained by an object as its height above ground level increases. As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy.

What happens to potential energy when you drop something? ›

As the ball falls towards the ground, its potential energy is transformed into kinetic energy, which will continue increasing as it gains momentum, until it finally collides with a surface.

What is the kinetic energy of a body falling downward? ›

Object Falling from Rest

As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. K.E. = J, which is of course equal to its initial potential energy.

What happens to the potential energy as the body moves downward? ›

As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
