The inertia of an object tends to cause an object:
$(a)$. to increase its speed
$(b)$. to decrease its speed
$(c)$. to resist a change in its state of motion
$(d)$. to decelerate due to friction

Academic Physics NCERT Class 9

The inertia of an object tends to cause an object to resist a change in its state of motion.

So, option $(c)$ is correct.

Give one example of a motion where an object does not change its speed but its direction of motion changes continuously.
Due to inertia the object will not change their state of rest or motion?
Give 3 examples of how force can: 1. Stop the motion of an object 2. Increase or decrease the speed of a moving object 3. Change the direction of motion of an object
Friction acts ________ to the motion of an object.
Order to reduce the loudness of a sound, we have to$(a)$. decrease its frequency of vibration of the sound$(b)$. increase its frequency of vibration of the sound$(c)$. decrease its amplitude of vibration of the sound$(d)$. increase its amplitude of vibration of the sound
The gravitational potential energy of an object is due to:a. its mass b. its acceleration due to gravity c. its height above the earth's surface d. all of the above.
A plane left 40 minutes late due to bad weather and in order to reach its destination, 1600 km away in time, it had to increase its speed by 400 km/hr from its usual speed. Find the usual speed of the plane.
The loudness of sound depends on$(a)$. its amplitude$(b)$. its time period$(c)$. its frequency$(d)$. its speed

The inertia of a moving object depends on:$(a)$. momentum of the object$(b)$. speed of the object$(c)$. mass of the object$(d)$. shape of the object
How is the weight of an object related to its mass?
Define ‘state of motion’ of an object. Name the ‘agent’ which can change the state of motion of an object.
A plane left 30 minutes late than its scheduled time and in order to reach the destination $1500\ km$ away in time, it had to increase its speed by $100\ km/h$ from the usual speed. Find its usual speed.
