SI unit of force is.........
Pa
N
J
W
The fixed object from where rest and motion of an object can be observed is called ............
a. Reference point
b. Stationary point
c. None of above two option
d. Both option 'a' and 'b' is right
Tick all the vector quantities in the list below.
Force
Length
Mass
Velocity
Acceleration
Mass is called a scalar quantity because it has only (a)
In the picture below which one is the displacement?
a. 1
b. 2
c. 3
d. 4
What is the formula to calculate speed?
Distance/time
Displacement/time
v-u/t
v+u/2
The formula to calculate velocity is ........
distance/time
displacement/time
v-u/t
v+u/t
If a car can travel 3000m in 2 minutes. What will be its speed?
(Note: Answer should be written with SI unit)
(a)
Which type of motion or velocity is shown in given diagram?
(a)
What are the formula to calculate average velocity?
(Note : There may be more than one answers.)
v-u/2
v+u/2
total displacement/total time
displacement/time
The rate of decrease in velocity is called.......
acceleration
Average velocity
Retardation
Uniform velocity
What will be the relative velocity of a body if two objects are travelling in same direction with same velocity?
(a)
What is the value of acceleration when the velocity is uniform?
10m/s²
0m/s²
9.8m/s²
None of above
When body starts to move from rest then its initial velocity will be........
1m/s
20m/s
0m/s
None of above
When a moving body applies brake and stops then its final velocity will be equal to........
1m/s
2m/s
10m/s
0m/s
When two bodies are travelling in different direction with velocity V m/s and Um/s then its relative velocity is calculated by using formula.
R = V x U
R = V + U
R = V - U
R = V ÷ U
What do you mean by negative acceleration?
(Note: There may be more than one answers. )
1. Retardation
2. Decreasing acceleration
3. Minus acceleration
4. That means -a
The mean of all velocity or the total displacement per total time is called (a)
A car is moving with the velocity of 25m/s. If the car comes to rest after 5 seconds, what is its retardation?
5m/s
5m/s²
-5m/s²
-5m/s
In which condition acceleration is not zero but body is in uniform motion?
when body is traveling straight
When body is in random motion
When body is in circular motion
All of above
