force

• aim - investigate how varying mass affects the the acceleration produced by a constant force
• 1 - use a toy car attached to a piece of string, the string is looped around a pulley and the other end is attached to a 100g mass, which will act as a force acting on the car. need a timer
• 2 - on the desk, draw chalk lines at equal intervals every 10cm
• 3 - hold toy car at starting point and let go. the resultant force acting through the string will cause the car to accelerate along desk
• 4 - record the time the car passes each distance marker
• 5 - repeat experiment by decreasing mass each time by 20g
• 6 - when taking away some mass, transfer that mass onto car to keep overall mass of object the same
