As the skateboarder accelerates, the ___________ energy store in the skateboarder's body decreases and the ___________ energy of the skateboarder increases.
The total mass of the skateboarder and skateboard is 60 kg60\text{ kg}60 kg. The speed of the skateboarder is 6 m/s6\text{ m/s}6 m/s.
Calculate the kinetic energy of the skateboarder and skateboard.
Use the equation: kinetic energy=0.5×mass×(speed)2\text{kinetic energy} = 0.5 \times \text{mass} \times (\text{speed})^2kinetic energy=0.5×mass×(speed)2
When the skateboarder drags their shoe on the ground to slow down, friction causes the temperature of the shoe sole to increase.
Calculate the change in thermal energy of the shoe sole.
Use the equation: change in thermal energy=mass×specific heat capacity×temperature change\text{change in thermal energy} = \text{mass} \times \text{specific heat capacity} \times \text{temperature change}change in thermal energy=mass×specific heat capacity×temperature change
How is the internal energy of the particles in the shoe sole affected by the increase in temperature?
