Kinematics

Yes, the Kelvin temperature of a substance is directly proportional to the average kinetic energy of the particles in the substance. The higher the temperature in Kelvins, the higher the average kinetic energy of the particles.

To convert from meters per hour (mPh) to kilometers per hour (km/h), you need to divide by 1,000.

So, 64 mPh is equal to 0.064 km/h.

Heat, from the friction in the brakes.

because you need to slide down the hill....?

The U.S. government lowered the speed limit to 55 miles per hour during the 1970s energy crisis in an effort to conserve fuel. This nationwide speed limit was part of a broader strategy to reduce oil consumption and dependency on foreign oil.

Types of motion include linear motion (movement in a straight line), circular motion (movement in a circular path), rotational motion (spinning or rotating around a central point), and oscillatory motion (repetitive back-and-forth motion).

100 mph = 146.6 feet per second.

You mean a force I guess. A force acting on an object will make it accelerate or decelerate, and if it is acting at an angle to the existing line of motion will make it change direction.

To convert 93 miles per hour to meters per second, you can use the conversion factor:

1 mile per hour is approximately equal to 0.447 meters per second.

Therefore, 93 miles per hour is approximately equal to 41.61 meters per second.

The energy that an object have due to its movement or position is called the mechanical energy. The total mechanical energy of an object is equal to the sum of the potential energy and kinetic of an object in an instant. The potential energy is dependent on the height from the ground and the mass of the object; Kinetic energy is dependent on the mass and the velocity of the object.

well, by definition vector is something that has both direction and magnitude, in this case weight is only countable when gravity exists, and of course gravity has direction

direction for vector doesnt have to be like north, south or within the plane because vectors are free and can be moved anywhere without changing its magnitude.

When the kinetic energy increases by four times, the speed of the body will double. The relationship between kinetic energy and speed is not linear, but rather quadratic. So if the kinetic energy increases by four times (2^2), the speed will increase by two times (2).

It's a 0th order tensor, also known as a scalar.

Vibrational kinetic energy is the energy due to vibrational motion :)

The formula for kinetic energy is KE = 0.5 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity. Rearranging the formula to solve for velocity, we get v = sqrt(2 * KE / m). Plugging in the values (KE = 160 J, m = 2.0 kg), we find that the basketball must be thrown with a velocity of approximately 8 m/s.

The decrease in kinetic and potential energy of the jumbo jet as it slows and descends on approach to landing is converted into other forms of energy such as heat and sound due to air resistance, and work done by the engines to counteract gravity and maintain the descent rate.

To find the net force acting on the car, we can use Newton's second law: [ F = ma ] where ( m = 1.20 \times 10^3 , \text{kg} ) and ( a ) can be calculated from the kinematic equation: [ d = \frac{1}{2} at^2 ] Given that the car starts from rest, the initial velocity is 0, so ( a = \frac{2d}{t^2} ). Substitute the values and solve for ( F ) to find the net force acting on the car.

Coal contains potential energy, which is energy that is stored within an object based on its position, composition, or state. When coal is burned, it releases this stored energy in the form of heat and light.

I believe it would be an application of E=mc2 except instead of c which is the speed of light we use v which is the speed of the car. so E will be KE in this case m will be 2000kg and v = 20 ms.

KE=mv2

KE=(2000 kg)(20m/s)^2

KE=(2000 kg) (400 m2/s2)

KE = (800, 000 J) or 800 kJ

The three basic types of acceleration is absolute (acceleration in a direction), angular (acceleration due to rotation) , and Coriolis (acceleration due to a point changing its distance from the center of rotation while spinning Eg. swirling toilet water.)

Hope this helps,

Speeding Up, Slowing Down, and Changing Direction

The range of a projectile is influenced by both the initial velocity and launch angle, while the height of the projectile is affected by the launch angle and initial height. Increasing the launch angle typically decreases the range but increases the maximum height of the projectile.

At the highest point in its trajectory, the vertical velocity of a projectile is zero. This is because the projectile has reached its peak height and is momentarily at rest before starting to descend.

what is difference between simple harmonic motion and vibratory motion?
