What would happen if a cyclist pedals harder?
Push harder on the pedals to increase the force pushing you forwards. Your speed will increase until the opposing forces increase to balance your larger forward force.
What forces are acting on a cyclist?
There are 4 forces that act on a cyclist and determine how fast the cyclist moves – propulsion, gravity, rolling resistance and aerodynamic drag. These four forces interact in various mixes with the conditions in which the cyclist is riding – wind, terrain, road surface, etc.
Does higher velocity mean higher force?
They CHANGE the speed. It would be better to say a greater force causes a greater CHANGE in velocity for an object. In that particular case, a greater gravitational force means that the planet must have a circular orbit with a greater speed.
What is the relationship between force-velocity and mass?
Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. This is Newton’s Second Law of Motion.
What is the relationship between power and velocity?
In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv. In a more general case where the velocity is not in the same direction as the force, then the scalar product of force and velocity must be used.
What is the relation between power and force?
Comparison chart
| Force | Power | |
|---|---|---|
| Symbol | F | P |
| Named After | Isaac Newton | James Watt |
| Derivations from other quantities | F = m a (force = mass multiplied by acceleration) | P = w/t (power = work divided by time) |
| Relation to “Work” | Force applied over a distance creates work. | Rate at which work is performed. |
