What is the combined mass of the bicycle and rider?
The combined mass of the bike and the rider is 85.0 kg. Choose a suitable system.
Does your answer depend on the mass of the bike and rider?
In part A, the answer depends on the total mass of the bike and the rider, as Kinetic energy = m v 2 2 \tfrac{mv^{2}}{2} 2mv2 .
What happens to the mechanical kinetic energy of a bicycle as the rider applies the brake and comes to a stop?
Explanation: The bike is has kinetic or motion energy when it is moving downhill. When brakes apply, the energy is transformed into thermal energy on your brake (heat) and sound energy since you can hear it.
Do the rider and bicycle have energy while coasting down the hill?
Yes, the rider and bicycle have energy when coasting down the hill because moving objects have energy.
Which forms of energy increase when a bicycle goes from slow to fast?
Which forms of energy increase when a bicycle goes from slow to fast? If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. A bicycle can convert up to 90 percent of a person’s energy and movement into kinetic energy.
Do the rider and bicycle have energy while coasting down the hill if so explain?
How does a bicycle wheel work?
Photo: Like a car wheel, a bicycle wheel is a speed multiplier. The pedals and gears turn the axle at the center. The axle turns only a short distance, but the leverage of the wheel means the outer rim turns much further in the same time. That’s how a wheel helps you go faster.
Can you generate electricity with a bicycle?
Pedaling a bike at a reasonable pace generates about 100 watts of power. That’s the same energy-per-time used by a 100-watt lightbulb. So if you pedaled eight hours every day for 30 days (no weekends off), then doing the math, you’d generate 24 kilowatt-hours (kWh) of energy.
Does riding a bike use energy?
When you ride a bicycle, several things happen that require energy and it’s transformation. You pedaling the bike is transforming chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. The chemical energy is potential and the mechanical energy is kinetic.
