Verification of Newton's Second Law

Materials Required:

1. Arrange the apparatus as shown in figure.

2. A suitable mass is hung on the weight hanger.

3. Release the weight on the weight hanger.

4. Start the timer to record the time of travel of the cart as it starts moving.

5. Note the distance moved and the time taken by the cart.

6. Calculate the acceleration of the object by equation a= 2S/t2.

7. Calculate M2g and (M1+M_{2})a.

8. Hence Newton’s Second Law is verified.

1. The simulation can be performed in three different environments –Earth, Uranus and Jupiter. To do this, choose any one of the above environments from the drop down box, ‘Select the environment’.

2. Select the desired vertical mass, M_{2} and Cart mass, M_{1} using respective slider.

3. Also select the desired distance by moving the slider.

4. Now, Click on the “Start” button to start the experiment.

5. Observe the time and note it down.

6. Using the time and distance calculate the acceleration of the object.

7. Also find M_{2}g and (M1+M2)a separately.

8. Hence Newton’s Second Law is verified.

Vertical Mass, M_{2} (g) Cart Mass, M_{1} (g) Distance travelled by the cart, S (cm) Time, t (s) Acceleration of the object, a= 2S/t^{2} (m/s^{2})

Calculation:

F= M_{2}g

M_{2}=……………………..g

M_{2}= ……………………….Kg

=…………………kg m/s^{2}

F= (M_{1}+M_{2})a

(M_{1}+M_{2}) =………………….g

(M1+M_{2}) =………………….kg

Calculate M2g and (M_{1}+M_{2})a. It is found to be same. Hence Newton’s Second Law of Motion is verified.
