What is the formula for calculating acceleration?
What is the formula for calculating acceleration? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Does constant velocity have to be in a straight line? Yes. Velocity […]

Do bulbs in series have the same brightness?
Do bulbs in series have the same brightness? Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in […]
What makes a real image?
What makes a real image? A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge.
