Why do you push harder on the pedals of the bicycle when first starting out than when moving at constant speed?

Basically, as a body accelerates, the forces acting upon it are unbalanced. However, as one reaches uniform speed (constant speed) you are no longer accelerating, so the forces acting upon the bike are now balanced. Newton's second law of motion states that when something is moving, it will continue to move at the same velocity until another force is applied (inertia). Because of this, the bike will be moving "on its own" after you stop peddling, so there is less need to pedal.

Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
Is gravity acting on a moving bicycle?
Of course.
In an isolated system Bicycle 1 and Bicycle 2 each with a mass of 10 kg collide Bicycle 1 was moving to the right at 5 ms while Bicycle 2 was moving to the left at 3 ms What is the magnitude o their?
Might be 20 kg-m/s
What is the difference between moving at a constant speed and not moving at all?
None, as "not moving at all" is just moving at a constant speed of zero. Special relativity shows that there is nothing unique or different about zero speed. It is just a value of constant speed.
Why is it easy to balance on a bicycle when its moving but not when it's stopped?
The turning wheels act as a gyroscope to keep the position constant (upright).
When riding a bicycle past a building you are not moving relative to the?
You are not moving relative to the bicycle.
How does inertia help a bicycle start?
it doesn't, in fact it makes it harder. Inertia resists change, so it makes it a bit difficult to get the bike moving.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
A truck and a bicycle have the same momentum which is harder to stop?
No way you have got to be kiding me everybody I know, knows the answer to that so here is the answer a BICYCLE!!!!!!!
Why do you keep moving forward when you slam on your brakes on a bicycle?
It is your momentum of moving forward that has to be overcome before your brakes can bring the bicycle to a stop.
If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
Is it easier to get going on a light bicycle or a heavy bicycle?
A light bike is easier to get moving.
Is gravity acting on a moving bicycle?
Of course.
A bicycle moving against traffic on the street is illegal?
Yes. You have to be traveling with the flow of traffic. A bicycle is considered a vehicle therefore all the same moving laws of a car apply to a bicycle while on the road.
What causes a bicycle to start moving?
You stir the paddles and the wheel start moving.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
