Physics problems for class 9 – numericals with solutions-set1 (CBSE / ICSE)


This set of Physics problems for class 9 students of CBSE/ICSE/HS boards cover Newton’s Laws of motion, Force, linear motion equations – kinematics, motion class 9 numericals and Gravitation (gravitational force). It covers vertical upward movement problems as well.

**New questions starting from 47 covers harder problems on motion under gravity. Also added problems on Pressure, Buoyant force and Buoyancy and conservation of momentum.

**In problems starting from 61, you will find new set of problems on kinematics and motion, a new set on simple pendulum, few interesting problems on relative density.
New problems on mirror (light) are added Q86 onwards.
Hope our readers & students will like this set and try to solve the numerical problems themselves.

I am providing the solutions as well, but you should try yourself every physics problem first.

The difficulty level is medium for most of the numericals. Surely these Physics problems for class 9set 1 will help to test your basics.

These problems not only help the students of high school, but also help many to face diverse competitive examinations. Let’s start with numericals on motion for class 9 with solution.

1) Force of 1000 Newton is applied on a 25 kg mass for 5 seconds. What would be its velocity?

 Solution:

F =1000 N
m=25kg
t= 5 sec
u=0
v=?

Acceleration = a = F/m = 1000/25 = 40 m/s

v = u + at =0 + 40X5 = 200 m/s

Physics problems class 9 – solutions: physics problems solved

2) A force is applied on a mass of 16 kg for 3 seconds. As the force is removed the mass moves 81 meter in 3 seconds. What was the value of the force applied?

Solution:

first 3 secs (Force is present)  –> next 3 secs (F is not there, so uniform velocity)

In the next 3 seconds the mass travels with uniform velocity (as there is no force that means no acceleration).

So the velocity in the next 3 secs:
V = 81/3 = 27 m/s

This velocity was attained in the first 3 seconds when the force was present.

So in the first 3 seconds, velocity changes from 0 to 27m/s.

Therefore the acceleration in first 3 seconds caused by the force present = (27-0)/3 = 9 m/s².

So the force applied on the mass for first 3 secs= mass x acc = 16 x 9 = 144 N

3) A mass of 50 kg was moving with a velocity 400 m/s. A force of 40000 N is applied on the mass and its velocity is reduced to 50 m/s after some time. What is the distance travelled by the mass during this period?

Solution:

Mass = 50 kg
u = 400 m/s
v= 50 m/s
F = 40000 N
t = unknown
Distance travelled in time t =?

Acceleration = a = F/m = 40000/50 = 800 m/s2

Again, acceleration a = change of velocity /t
or, t = change of velocity/a = 350/800 sec

Distance travelled: s = ut – (1/2)a t2

= 400 * (350/800) – (1/2) 800. (350/800)2
= 175 – 76.5 = 98.5 m

                                                                                           Physics problems for class 9 with solutions – physics problems solved

Mass = 150 gram = 150/1000 kg = 0.15 kg

Change of velocity = 20 – (-12) = 32 m/s

T = 0.01 sec

Acceleration = change in velocity / time = 32/0.01 = 3200 m/s2

Force = mass X acc = 0.15 X 3200 N= 480 N.

solutions: continued

5) Momentum of an object changes from 100 kgm/s to 200 kgm/s in 2 seconds. What is the force applied on it?

Solution:
Note:Force = ma = m(v-u)/t = (mv – mu)/t = change of momentum /time = rate of change of momentum

Force= change of momentum /time = (200-100)/2 = 100/2 = 50 N

physics numerical – Physics with solutions

6) A force of 200 N is applied on a body and its velocity changes from 5m/s to 10m/s in a second. What is the mass of the body?

Solution:

mass = force/acceleration
here acceleration =a = (10-5)/1 = 5 m/s2
so, mass  = 200/5 kg = 40 kg

solutions: continued

7) A mass of 1 kg is moving from east to west with a velocity 10 m/s. A force is applied on it for 2 seconds and its velocity becomes 5 m/s. What is the value and direction of the force?

Solution:

Mass = 1kg
velocity = 10 m/s (east to west)
Because of the force the velocity reduces to 5 m/s in 2 secs.
acceleration = change of vel/time=5/2 = 2.5 m/s2

Force = mass X acceleration= 1 X 2.5 = 2.5 N.
As the velocity reduces because of force, (negative acc i.e. retardation) hence the direction of the force would be opposite to the initial direction. So direction of force will be west to east.

solutions: continued

8) If the distance between 2 objects is doubled then how will the gravitational force between them change?

Solution:
F1 = GMm/r2
F2 = GMm/(2r)2
= GMm/4r2
so F2/F1 = ¼ ,
so the final gravitational force will be ¼ th of the initial gravitational force

solutions: continued

9) If the distance between 2 objects is halved then how will the gravitational force between them change?

Solution:
F1 = GMm/r2
F2 = GMm/(r/2)2
=4 GMm/r2

so F2/F1 = 4/1
so the final gravitational force will be 4 times of the initial gravitational force

10) If the masses of the 2 objects are doubled then how will the gravitational force between them change?

Solution:

F1 = GMm/r2
F2 = (G2M2m)/(r)2
=4 GMm/r2
so F2/F1 = 4/1
so the final gravitational force will be 4 times of the initial gravitational force
