... (iv) At time t = 0 s, the only resistive force acting is (static) friction. When time increases to 30s, the cycle and the cyclist picks up speed (i.e. accelerates due to the resultant force acting on them). This causes the air resistance acting them to increase, since magnitude of air resistance inc ...

... • Newton’s second law (the law of acceleration) – When a net force acts on an object, the object will accelerate. The acceleration is directly proportional to the net force and inversely proportional to the mass. • Newton’s third law (the law of action and reaction) – Whenever one object exerts a fo ...

... acceleration of the electron should remain constant because the ratio of force to mass does not change. In fact, experiments show that the acceleration of the electron decreases as its velocity increases. Describe what can be deduced from such experiments about the nature of accelerated electrons. ...
