Because their speed might remain constant, but their velocity doesn't. Remember, velocity is a vector, so it has magnitude (which is the speed of the object), but also direction. For an object moving in a...

If you've been given the angle the vector makes with an axis, you can find the component of the vector parallel to that axis by multiplying the size of the vector by the cosine of the angle it makes with ...

If an object has no resultant force acting upon it then it is moving at a constant speed. Acceleration is a vector quantity meaning that it includes magnitude and direction. When it is moving around a cir...

Through energy conservation, we can determine that no energy is lost and thereforeKinetic energy = Electrical energyAs a result the following equation is present where both sides represent energy:(m*(v^2)...

Before heating: Ice and air present in the tin, the ice particles vibrate about fixed positions, they do not exert a pressure on the lid at this time, air particles inside the tin hit the lid but exert th...
