Question

Students perform two experiments using toy cars For each experiment the students measure: the mass* of the toy cars . the amount of force applied to the cars . the speed of the cars after 4 seconds A. Place either Force or the Mass into the box to identify which effect is being tested for each of the two tables B. Place numbers into the blank boxes in the tables to infer the final speed of the car in each trial Place only one number in each blank box. . You may use each number more than once. *mass/weight DRAG DROP VALUES Experiment t1 Testing the Effect of Mass Mass of Car Applied Final Speed (o) Force (N) (m/s) 500 32 8 16 500 2 16 Experiment2 Force Testing the Effect of Applied Final Speed ↓ of Car (g) 500 1.000 Mass Trial (m/s) 16 Force (N) 2

Answer 1

Answer)

We know that

Force = mass * acceleration

And velocity = acceleration*time

Time = 4 seconds (given)

1) mass = 500, force = 1,t = 4

1 = 0.5*acceleration

Acceleration = 1/0.5 = 2 (500 grams = 0.5 kg)

Speed = acceleration*time = 2*4 = 8

2) mass = 500, 0.5 , force = 2, t = 4

2 = 0.5*a

A = 2/0.5 = 4

Speed = 4*4 = 16 m/s

1) when mass = 500 and, force = 2

Speed = 16

2) when mass = 1000 and force = 2

2 = 1*a

A= 2

Speed = 2*4 = 8

{A = acceleration}

{Speed = velocity}
