Do you think a moving skateboard has energy? Why or Why not? What about a skateboard that is not moving?

Yes,

because it is moving which generates energy. ... Does a moving skateboard have energy? To move the energy, you had to transfer the potential energy to kinetic energy. This generates heat, light, or sound.

A ball, which has a mass of 1.25 kg, is thrown straight up from the top of a building 225 meters tall with a velocity of 52.0 m/
Elena-2011 [213]

First we will find the speed of the ball just before it will hit the floor

so in order to find the speed of the cart we will first use energy conservation

KE_i + PE_i = KE_f + PE_f

\frac{1}{2}mv_i^2 + mgh = \frac{1}{2}mv_f^2 + 0

\frac{1}{2}(1.25)(52)^2 + 1.25(9.8)(225) = \frac{1}{2}(1.25)v_f^2

So by solving above equation we will have

v_f = 84.3 m/s

now in order to find the momentum we can use

P = mv

P = 1.25 \times 84.3

P = 105.4 kg m/s

A circuit contains a 1.5 volt battery and a bulb with a resistance of 3 ohms. Calculate the current
Vitek1552 [10]

The formula that links voltage (V), resistance (R) and current intensity (I) is

V=RI

Solve this formula for I to get

I=\dfrac{V}{R}

Plug your values for V and R and you'll get the current.

Gravity __________ your kinetic energy when you are driving uphill and __________it when you are driving downhill.
Oxana [17]
Gravity decreases your kinetic energy when you are driving uphill since the direction of motion is opposite for both. Driving uphill is force going upward while gravity pulls object down. When it is going downhill, the car tends to go faster since the gravity helps the object to go down by adding another value to the total acceleration of the motion of the object. Using the forces of balance, an object going up tends to become heavier while object going down tends to become lighter because of the gravity factor. Another analogy is the motion of elevators going up and down that incurs effects to your weiight.
