Newton's Laws RQP- effect of varying force on acceleration and of varying mass on acceleration

Question 1

varying force on a constant massed object on acceleration

apparatus

Answer 1

• toy car attached to string
• string looped around a pulley with a 100g mass on the end (force)
• on a table with chalk lines every 10cm
• timer

Question 2

varying force on a constant massed object on acceleration

step 1

Answer 2

put car at starting point (0cm)

Question 3

varying force on a constant massed object on acceleration

step 2

Answer 3

let go of the car (it will accelerate along the bench)

Question 4

varying force on a constant massed object on acceleration

step 3

Answer 4

record the time that the car passes for each distance marker

Question 5

varying force on a constant massed object on acceleration

step 4

Answer 5

repeat experiment but decrease the mass of the end of the string (e.g. 80, 60, 40, 20g) but adding the weight taken off to the toy car to keep the mass of the object constant

Question 6

varying mass of an object on acceleration produced by a constant force

step 1

Answer 6

keep force constant by using 100g mass on end of string

Question 7

varying mass of an object on acceleration produced by a constant force

step 2

Answer 7

attach a mass to the toy car e.g. 200g

Question 8

varying mass of an object on acceleration produced by a constant force

step 3

Answer 8

record time car takes to accelerate for each distance marker

Question 9

varying mass of an object on acceleration produced by a constant force

step 4

Answer 9

repeat experiment, increasing mass attached to the toy car
