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.
What else can I help you with?
Which describes a bicycle going at a constant speed in a constant direction?
A bicycle moving at a constant speed in a constant direction has no changes in its velocity or acceleration. It is a balanced state of motion where the bike maintains its speed and direction without any external forces acting on it.
Which describes the average velocity of a bicycle going at a constant speed in a constant direction?
Every time the unicycle returns to its starting point, the average velocity equals zero. C. The total displacement divided by the time.
A bicycle is moving with constant velocity to the east. What is true of the applied forces?
The applied forces on the bicycle would be balanced. The force applied by the rider in pedaling is equal and opposite to the forces of friction and air resistance acting on the bicycle. This results in a net force of zero, allowing the bicycle to move with constant velocity.
Where is the net force on a bicycle zero?
The net force on a bicycle is zero when the forces pushing forward (such as pedaling and friction) are balanced by the forces resisting motion (such as air resistance and friction). This typically occurs when the bicycle is moving at a constant speed on a level surface.
Why it is easy to stop moving bicycle then the moving car with same speed?
It is easier to stop a bicycle than a car with the same speed because the bicycle has less mass and momentum compared to the car. The car's greater mass and momentum make it harder to stop quickly. The car's brakes also have to work against greater inertia, requiring more force and distance to stop.

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.

What is the word for not moving or moving at a constant speed in the same direction?
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
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!!!!!!!
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.
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.
