Activity 6.3 Let us experiment (Demonstration activity)

Aim: To see the impact of applied force on acceleration of object.

Procedure: Two objects (cardboard cart and paper cup) of mass m₁ and m₂ are connected through thread and placed on smooth horizontal table through a pulley.

Let force F applies on paper cup of mass m₂. The cup moves down due to gravitational force by Earth and thread will pull the cart with a constant force.

Note the time taken T₁ by cart to reach the end of table.

Increase the mass of paper cup and note the time taken T₂ by cart to reach the end of table.

If a₁ and a₂ are accelerations in two scenario, then s = [latex]\frac{1}{2}[/latex]a₁T₁² = [latex]\frac{1}{2}[/latex] a₂T₂²

Conclusion: Acceleration of an object of mass m increases as the net force applied on it increases.
