What forces affect kinetic energy

1 answer:

4 0

Many factors affect potential and kinetic energy. Kinetic energy is energy in motion, while potential energy is energy that hasn't happened yet. ... Kinetic energy is the energy an object produces when moving. Due to gravity, kinetic energy is affected by the object's mass and velocity.

Describe the differences between the change in momentum when a car is stopped with the brakes and when a car is stopped in a col

tresset_1 [31]

Explanation:

When a car is breaking, the brakes apply pressure/force onto the wheels(car) which allows it to slow down.

When the car collides with an object, it is exerting a force upon that object to which it applies an equal and opposite force on the car.

I think this is what you are asking for.

Hope This Helps :)

What do radio waves and gamma rays have in common?

Nastasia [14]

Answer:

A - They are both electromagnetic waves.

Explanation:

Electromagnetic waves are waves consisting of periodic oscillations of electric and magnetic fields, that vibrate in a plane perpendicular to the direction of propagation of the wave (for this reason, they are said to be "transverse waves").

Electromagnetic waves, unlike mechanical waves, can travel through a vacuum, and do not need a medium to propagate. Their speed in a vacuum is a constant and it is called speed of light ( $c=3.0\cdot 10^8 m/s$ ).

Electromagnetic waves are classified, depending on their wavelength and frequency, into 7 different types - together they form the electromagnetic spectrum. The 7 types, listed from shortest to longest wavelength, are:

gamma rays

X-rays

ultraviolet radiation

visible light

infrared radiation

microwaves

radio waves

All these waves, despite having different properties, are all electromagnetic waves -so we see that both radio waves and gamma rays belong to this type of waves.

Finger [1]

Complete question :

NASA is concerned about the ability of a future lunar outpost to store the supplies necessary to support the astronauts. The supply storage area of the lunar outpost, where gravity is 1.63 m/s2, can only support 1 x 10^5 N. What is the maximum WEIGHT of supplies, as measured on EARTH, NASA should plan on sending to the lunar outpost

Answer:

601,220N

Explanation:

Given that:

Gravity at lunar outpost = 1.63m/s²

Acceleration due to gravity on earth = 9.8m/s²

Supported weight = 1 * 10^5 N

Maximum weight of supplies as measured on earth;

(Ratio of the gravities) * weight of supplies

(9.8m/s² / 1.63m/s²) * (1 * 10^5 N)

6.0122 * (1 * 10^5)

6.0122 * 10^5 N

= 601,220 N
