What causes a ball rolling across the floor to slow down low of motion​

Physics
1 answer:
Savatey [412]3 years ago
3 0

Answer:

Friction is a force that slows down moving objects. If you roll a ball across a shaggy rug, you can see that there are lumps and bumps in the rug that make the ball slow down. The rubbing, or friction, between the ball and the rug is what makes the ball stop rolling.

4) Kinetic energy is directly related to _______
TEA [102]

Answer:

4) C.mass

5) C. Potential Energy

Explanation:

4) Kinetic energy (KE) of an object is the energy that it possesses due to its motion. If a mass is in motion ,it has a kinetic energy .

By definition

Kinetic.Energy=\frac{1}{2}*mass*velocity^{2}

what matters in Kinetic energy is the mass and the velocity only .

there fore the answer is

C.mass

5) Potential energy is the energy stored in an object, due to the object's position or arrangement.

By definition

Potential.Energy=mass*gravitaional.Acceleration*height

in potential energy the height matters.higher the height , higher the energy

therefore the answer is

C.Potential Energy

A toy of mass 0.155 kg is undergoing simple harmonic motion (SHM) on the end of a horizontal spring with force constant 305 N/m
zzz [600]

Answer:

310.38\times 10^{-4}j

Explanation:

We have given mass m=0.155 kg

Force constant K = 305 N/m

Distance X=1.25\times 10^{-2}m

Velocity v=.305 m/sec

The total energy at any position of the motion is give by E=\frac{1}{2}mv^2+KX^2  here \frac{1}{2}mv^2 is energy due to motion and KX^2  is energy due to spring elongation

So total energy E=\frac{1}{2}\times 0.155\times 0.305^2+305\times 0.0125^2=310.38\times 10^{-4}j

katrin [286]

'A' and 'C' talk about energy being created and destroyed.  That can't happen.

'D' trailed off in the middle, and we don't know WHAT it was talking about.

'B' is the only correct statement.
