Answer: Friction also prevents an object from starting to move, such as a shoe placed on a ramp. When friction acts between two surfaces that are moving over each other, some kinetic energy is transformed into heat energy. Friction can sometimes be useful.
Explanation:
Answer:
An effect whereby a mass moving in a rotating system experienced a force acting perpendicular to the direction of motion and to the axis of rotation.
How do you find instantaneous velocity
Select a point on a distance-time curve graph. Draw a tangent to the curve at that point. Tangent -> hypotenuse of right angled triangle. Opp/adjacent in graph units is vel at that point -> in distance and/or time
KE = (1/2)·(mass)·(speed)²
It doesn't matter whether the object is in a car, on a boat,
falling, on a conveyor belt, or being carried by ants.
KE = (1/2)·(40 kg)·(2 m/s)²
KE = (20 kg)·(4 m²/s²)
KE = 80 kg-m²/s²
KE = 80 Joules
I'm pretty sure your answer should be Bonds. Hope this helps! =^-^= (Maybe brainliest please?)
