It can be observed that the period of oscillation is independent of both mass and initial displacement, but does depend on length. According ...

... grandfather, James, dies and James left him nothing in his will. There is also no doubt that Isaac felt very bitter towards his mother and stepfather. When he was reflecting on his sins at age 19 he wrote: "Threatening my ...

... of the sixteenth and seventeenth centuries Galileo died, and Newton was born, in 1642. That was a time of terrible religious persecution. During their lives, 50,000 women were accused of witchcraft and burned alive. Nineteen witch hangings in Salem were small ...

... factors which have a direct effect upon the amount of air resistance are: - the speed of the object - the cross-sectional area of the object Increased speeds and increased cross-sectional areas result in an increased amount of air resistance. Gravity is what causes ...

... front edge of the wings are designed to be slightly higher than the rear of the wings, and the wings must also curve downwards. The angle of the wings to the horizontal is called the angle of attack. This helps ...

... force exerted by electrostatic charge is called Electrostatic force. This type of force can be repulsive or attractive. For e.g. Rub a comb with a dry cloth and bring it near small pieces of paper. We would be astonished to ...

... the clamp. We found out that this could be the best thing to vary. The reasons for this is because we could choose whether to have the ruler further away from the desk and have it bend more or have ...

... force is that force which only affects the speed of an object and not the direction. Friction is the force that happens when two things rub together. The effect of friction is usually to slow you down. With less friction, ...
