What else can I help you with?
Can a bicycle or a ball get up speed instantaneously?
yes but if they are going down road
How a bicycle kinetic energy changes when that bicycle slows down?
As a bicycle slows down, its kinetic energy decreases. This is because kinetic energy is directly proportional to an object's velocity squared, so as the bike's speed decreases, so does its kinetic energy. The energy is either dissipated as heat due to friction from the brakes, or stored temporarily as potential energy if the bicycle is going uphill.
Which force causes a bicycle to slow down when the brake are used?
That is called friction.
What is the effect of the weight of the wheel of the bicycle to its speed?
It really does not have an effect on the maximum speed, but due to inertia, it does inhibit [slow down] changes [acceleration or deceleration] in speed.
How does brakes and steering of a bicycle help with speed?
When going down a hill, you will pick up much more speed than if on flat roads. If you don't have brakes, you have very little chance of slowing down if something/someone goes infront of your path. The handlebars of a bike don't really affect the speed of the bike, that is more to do with navigation.
What force causes a bicycle to slow down when the brake is used?
Friction between the brake pads and the wheel rim or disc generates the force that slows down a bicycle when the brakes are applied. This friction converts the kinetic energy of the moving bicycle into heat, causing it to decelerate.
What are the two forces act slowing down our bicycle from sloping downhill?
The two forces acting to slow down a bicycle going downhill are frictional force, generated between the tires and the road surface, and air resistance, caused by the bike moving through the air. These forces oppose the bike's forward motion and contribute to decreasing its speed.
What causes the speed of a sled to increase or decrease when going down a hill?
The speed of a sled increases when going down a hill due to the force of gravity pulling it downhill. The speed decreases when there is friction between the sled and the surface of the hill, air resistance, or when the slope becomes less steep.
Can you slow down the bicycle by changing the gear?
No. Simply changing the gear without doing anything else won't slow a bicycle down. You can coast along without peddling and that will slow you down or you can use the brakes to slow the bike. Changing gears will affect the speed only if the current speed is slower than the highest speed you can reasonably attain with the selected gear - changing to a higher gear will help you speed up.
Does changing the height of a ramp affect the speed of the car going down the ramp?
Changing the slope of the ramp will affect the speed of the vehicle going down it.
What is the actual speed of a bicycle?
I have clock 30 to 40 MPH going down hill on some of the Welsh mountain passes. But, usually, on the flat, I would average 12 to 15 MPH. Even less if into a headwind.
What causes your bicycle tire to wear down?
Extreme braking and low inflation cause wear on a bike tire.
