H Exp – Mechanics 09 – Lifts

Aim – To calculate the acceleration of a lift

Instructions

▪ Use the scales to determine the weight in newtons (N) and the mass in kilograms (kg) of the student when the lift is stationary
▪ Press the button the send the lift upwards
▪ Note the maximum reading on the scales as the lift accelerates upwards
▪ Note the reading as the lift is travelling at constant speed
▪ Note the minimum reading as the lift decelerates to a halt
▪ Repeat the experiment for the downwards journey of the lift
▪ Use the results to calculate the acceleration of the lift at the three stages of each journey
