science quiz for class 9 Question list
If the car is moving in a straight line
If the car is moving on circular road
If the pendulum is moving to and fro
If a planet is moving around the sun
When a car runs on a circular track with a uniform speed, its velocity is said to be changing. This is because:
The car has uniform acceleration
The direction of car varies continuously
The car travels unequal distance in equal interval of time
The car travels equal distance in unequal interval of time
The inertia of an object tends to cause an object:
to increase its speed
to decrease its speed
to resist a change in its state of motion
to decelerate due to fiction
In case of negative workdone, the angle between the force and displacement is:
0 degree
45 degree
90 degree
180 degree
A car is accelerated on a levelled road and attains a speed of 4 times of its initial speed. In this process the kinetic energy of the car:
does not change
become 4 times that of initial kinetic energy
become 8 times that of initial kinetic energy
become 16 times that of initial kinetic energy
The workdone on an object does not depend on the:
displacement
angle between force and displacement
force applied
initial velocity of the object
