Acceleration RP7

Question 1

How do you set up the Acceleration practical?

Answer 1

A toy car on a table attached to string which leads to a pulley which holds an 100g mass. Draw chalk lines on the table at regular intervals
A timer

Question 2

Once the mass is let go, what should u do?

Answer 2

Record the time it takes the car to reach each chalk line
If the acceleration is very quick you may wish to use a phone to record it and play it back to make it easier

Question 3

What is the independent variable in this experiment?

Answer 3

The mass attached to the string

Question 4

What is the control variable in this experiment?

Answer 4

The mass of the object( the car, string and the mass attached)

Question 5

What is the dependant variable in this experiment?

Answer 5

How force affects the acceleration of the object

Question 6

How do you keep the mass of the object the same when u change the mass attached to the string?

Answer 6

If you decrease the mass attached by one value you have to attach a mass to the toy car of the same value

Question 7

What does Newtons 2nd law of motion tells us about the relationship between the acceleration of an object and the force applied?

Answer 7

They are directly proportional to

Question 8

In this experiment, what is the force?

Answer 8

The mass on the end of the string

Question 9

What does Newtons 2nd law of motion tells us about the relationship between acceleration of an object and mass of the object?

Answer 9

They are inversely proportional

Question 10

If you increase the mass of the toy car what happens to the acceleration?

Answer 10

It decreases
