Question 1. Draw graphs to show the dependence of

(i) acceleration on force for a constant mass and

(ii) force on mass for a constant acceleration.

Answer:

(i) acceleration on force for a constant mass and

(i) acceleration on force for a constant mass and

(ii) force on mass for a constant acceleration.

force on mass for a constant acceleration

Question 2. How does the acceleration produced by a given force depend on the mass of the body? Draw a graph to show it.

Answer:

If a given force is applied on bodies of different masses, then the acceleration produced in them is inversely proportional to their masses.

A graph plotted for acceleration (a) against mass (m) is a hyperbola.

A graph plotted for acceleration (a) against mass (m) is a hyperbola

Question 3. How does acceleration vary with the force applied for a given body ? Show it with the help of a graph.

Answer:

Acceleration produced in a body of given mass is directly proportional to the force applied on it. i.e., a ∝ F (if mass remains constant)

The graph plotted for acceleration a against force F is a straight line as shown below:
