Friction makes a moving object slow down

Type of friction: Air resistance

Surface with most friction is surface 2 because the cup is the highest up

Option 2 is the one that makes the car go forward

ice has the least friction

A 1500kg car double its speed from 50km/h to 100km/h. By how many times does the kinetic energy from the car's forward motion in
Rashid [163]

Answer:

Explanation:

Inital KE = (1/2) m v^2 = (1/2) * 1500 * 50^2 = 1,875,000 J  

Final KE = (1/2) * 1500 * 100^2 = 7,500,000 J  

But  ,

4 * 1875000 = 7500000

so the KE has increased by 4 times.

Which is the force of repulsion between two positively-charged particles?
klio [65]
<span> answer>>>>electric force <<<<by the way i don't like physics but i answer this for you ^-^</span>


<span>This is because centripetal force is just the net force of a circular motion. There are no attractive or repulsive forces here. This is not the case here. </span>
<span>The gravitational force is a force reliant on mass and attraction of the masses. There are attractive forces here, but not really repulsive forces. </span>
<span>The electric force is the only one that would make sense because it has to do with a relationship between charges and includes both repulsive and attractive forces.</span>

What is the difference between current and voltage besides their units of measurement
kondor19780726 [428]
"Voltage" is the "pressure" that makes electrons want to leave where they are
and head in some direction, if there's conducting material in that direction.

"Current" is the rate at which they all migrate in that direction.
