Activity 8.8 Class 9 Science

    ·     In your everyday life, you come across a range of motions in which

    a.  Acceleration is in the direction of motion.

    b. Acceleration is against the direction of motion.

    c.  Acceleration is uniform.

    d. Acceleration is non-uniform.

    Can you identify one example of each of the above types of motion?

Activity 8.8 Class 9 Science Explanation

(a)       If the speed of a bus or car increases then the acceleration of the bus is in the direction of motion.

(b)      If the brakes are applied, the speed of the bus decreases, then the acceleration is against the direction of motion.

(c)       The acceleration of a freely falling body under gravity is uniform.

(d)      If a bus is passing through a congested road, it accelerates or retards, then acceleration is said to be non-uniform.

Acceleration – A change in velocity in a unit of time is called acceleration. It is a vector quantity.

 

Activity 8.8 Class 9 Science Conclusion

It is concluded that motion can be uniform or non-uniform. So acceleration is uniform and non-uniform.
