Why can you exert greater force on the pedals of bicycle if you pull up on the handlebars?
because the muscles in your arms pulling on the handle bars causes an equal and opposite reaction from the bars acting on your arms in a direction toward the bike. this force counteracts some of the upward force from the equal and opposite reaction from the pedals due to you pushing down with your feet. in other words, it allows you to counter some of the force by involving muscle from your arm in the force to hold you down to the bike
Why does the cyclist have to keep pedalling to maintain their constant velocity?
because the force of friction at the wheels to ground is slowing it down
What force causes a yo yo to slow down and stop?
inertia
What is main force tht causes a to to roll down a ramp?
Gravity
What causes objects to speed up or slow down?
an outside/net force
How do you train for biking?
i learnt how to bike on a hill. My dad held my bike and then let me go. It takes a lot of times to master it but while your going down the hill, you should try pedalling!
Why can you keep on getting faster and faster when you ride on a bike even thought you have stopped pedalling?
This can only happen if you are travelling on a slope (downwards) or if some other force is pushing you to accelerate, perhaps wind or somebody or something is pushing you faster. If you are on flat ground and nothing else is propelling you, then you WILL slow down and come to a stop, eventually. Friction causes that.
When you pedal really fast on a bike you can feel the wind slowing you down. Which force causes this?
It's usually referred to as air resistance.

How do riding a bike up a hill stand up help you?
It helps in two ways:it changes the pedalling motion to something that's pretty much like you're stepping up on to the pedals like you're climbing a set of stairs. This use a slightly different set of muscles than seated pedalling which is good if you're getting tired.it puts your whole body in a position where you can actually brace yourself against the bars to push even harder against the pedals. If it wasn't for the bars, the hardest you could ever push would be the same as your weight, but when you're simultaneously pulling the bike up while pushing down you can generate more force. A variation of this is when the rider tips the bike from side to side in synch with his pedalling.
Why does a spinning top move in a circular path?
The spinning top is perturbed by gravity pulling it down and this causes the top to move in a direction perpendicular to the down force this is an example of vector motion. IJ=k.This is similar to riding a bike and as you lean on the bike you turn around the corner.
What is a good bike exercise fitness plan?
Warm up for a good five minutes, then vigorously pedal for about a half hour constantly if you can. Afterwards, cool down for five more minutes with light pedalling.

What force pulls a bike downhill?
The force of Gravity. Gravity is the force that pulls everything down to the ground. Hope this helps!
What force causes water to go down the drain?
gravity force
What force is acting if you fall from a bike?
gravity it pulls all objects down
Which is the main force that causes a toy car to roll down a ramp?
The gravitational force is.
