There are three kinds of levers. What makes them different from each other?

Answers

Answer 1

Answer: Every lever and every class has a fulcrum, load, and effort. It helps move a heavy load.

Class one is when the fulcrum is the main acting force to help carry this weight.

Class two is when the person needs to put more effort to carry a weight.

Class three is when load itself helps carry a weight.

It all depends where the load, effort, and fulcrum are located. If the fulcrum is in the middle, it would be the most supportive force. If the fulcrum was at an edge, the effort or load would be the main forces of carrying, depending on their location. Location is important.

They all work synergistically to carry different things. They all help carry, but the different classes seperate them by fulcrum, effort, and load. Also note that the fulcrum is a very important part of a lever, without it, carrying a big box would be very heavy in the absence of a handler.

FULCRUM is the most important part! Remember that!

Answer 2

Answer: 1. Seesaw . Fulcrum Middle That balances it
2. Wheelbarrow . Fulcrum is the wheel. Input = handles Output = objects inside wheelbarrow
3. Baseball bat . Fulcrum is the hands. Input = Bottom section of the bat. Output = top section of the bat with more force.

What is the potential energy of a 2-kilogram potted plant that is on a 1 meter-high plant stand?

Answers

Potential energy is the energy stored by an object due to its position or arrangement.

The potential energy of the potted plant is 19.6 joule.

What is the potential energy?

Potential energy is the energy stored by an object due to its position or arrangement.

It can be given as,

$U=mgh$

Here, $m$ is the mass of the object, $g$ is the gravitational force experienced by the object and $h$ is the height.

Given information-

The mass of the potted plant is 2 kilogram.

The height of the plant stand is 1 meter.

The value of the gravity force is 9.81 meter per second squared on the surface of the earth.

To find the potential energy put the values in the above formula as,

$U=2*9.81*1\nU=19.6$

Hence the potential energy of the potted plant is 19.6 joule.

Final answer:

The potential energy of a 2-kilogram potted plant on a 1 meter-high plant stand is 19.6 J.

Explanation:

The potential energy of a 2-kilogram potted plant on a 1 meter-high plant stand can be calculated using the gravitational potential energy formula:

PE = mgh

Where:

PE is the potential energy
m is the mass (2 kg)
g is the acceleration due to gravity (9.8 m/s²)
h is the height (1 meter)

Substituting the values into the formula:

PE = (2 kg)(9.8 m/s²)(1 meter) = 19.6 J

Define circular motion and give some examples.

Answers

"Circular motion" is motion in a circular path.

-- Any point on the tire of a bicycle or a car that is moving.

-- Any point on the hour, minute, or seconds-hand of an 'analog' clock.

-- The ball in the roulette wheel before it comes to a stop.

-- Any point on the rim of the Wheel of Fortune before it stops.

-- Any point on any propeller of a windmill, when the wind is blowing.

MOTION OF THE BODY CIRCULAR PATH IS CALLED CIRCULAR MOTION

FEW IMP POINTS ABOUT IT :-

‌A tengential is always responsible for change in speed
‌If the Direction of acc and velocity is same then body's speed inc
‌If they r in oppsite direction then Body's speed dec .
‌If speed becomes constant then tangential acc become zero .
‌By the basis of tangial acc the circular motion is divided into two types uniform circular motion and non uniform circular motion

${ \blue {\bold{UNIFORM \: CIRCULAR}}} \n \green{ \bold{ MOTION}}$

‌when object in a circular path in a constant speed or constant circular speed is called uniform circular motion.
‌In case of uniform circular motion acc tendial will be zero
‌In case of uniform circular motion acc centripetal will be equal to net acc.

${ \green{ \bold{ NON UNIFORM}}} \n {\blue{ \bold{CIRCULAR \: MOTION}}}$

‌Centripetal acc is not equal net acc
