What happens when the speed of an object increase without change in height in the potential energy?

You're describing an increase in the object's kinetic energy, which depends
on speed, and no change in its potential energy, which depends on height.

A quarterback pedals 3.3meters southward and then run 5.7meters northward. Whats the distance ? And whats the displacement?
masya89 [10]
The distance is 9.0 meters because that's how far the person ran. The displacement is 2.4 meters North because displacement is a speed AND direction. Basically you're calculating how far you are from where you started.

The evil team of Ms. Moonstruck and Mr. Luny intend to deflect the Moon from its orbit around Earth by pulling it with a force o
BabaBlast [244]

Answer:

92867kg

Explanation:

DATA:

mass of the moon 'm_1'= 7.36 x 10^2^2kg

mass of the mini black hole 'm_2'=?

universal gravitational constant= 6.67x10^-^1^1 Nm²/kg²

distance 'r'= 7.47×10^6 m

force 'F'= 8170N

Newton's Law of Universal Gravitation is given by:

F=G\frac{m_1m_2}{r^2}

m_2=\frac{(8170)(7.47*10^6)^2}{(6.67*10^-^1^1)(7.36*10^2^2)}

m_2=92867kg

Dovator [93]

Answer:

Imagine you have an orange. This is your imaginary Earth. When you look at it in any direction, you won’t be able to see all sides of it. But when you peel the orange, flatten and stretch it out, you can begin to see everything.

Similarly, a map projection is a method by which cartographers translate a sphere or globe into a two-dimensional representation. In other words, a map projection systematically renders a 3D ellipsoid (or spheroid) of Earth to a 2D map surface.

PLEASE HELP!! Newtons first law states that if an objects velocity is changing a __________ must be acting on it. Question 1 opt
Anika [276]

Newtons first law states that if an objects velocity is changing a <u>force</u> must be acting on it.

Explanation:

Newton's first law of motion states that:

"An object at rest (or in uniform motion) will remain at rest (or will continue moving with the same velocity) unless acted upon an unbalanced force"

We can apply this law to a daily life example:

  • Take a book at rest on a table: the forces acting on the book are balanced. If we do not apply any other force, we know that the book will remain at rest: this is exactly what is summarized in Newton's first law.
  • Take a space probe moving in the interstellar space, very far from any planet or source of gravitational force. Since there are no forces acting on the proble, the probe will continue moving at the same velocity (same speed and same direction) forever, unless stopped by a new force acting on it.

This means that in order to put an object at rest in motion, or to stop an object already in motion, or to change its velocity, an unbalanced force needs to be applied: otherwise, the object will continue having the same velocity (which can be either zero or non-zero), so it will continue having  same speed and same direction.
