//Multiple Choice

What is the SI unit of speed?
{
= m/s
~ km
~ second
~ meter
}

Which type of motion covers equal distances in equal time intervals?
{
~ Random
= Uniform
~ Non uniform
~ variable
}

What is the term for the total distance divided by total time?
{
~ Constant speed
~ Displacement
~ relative velocity
= Average speed
}


Which of the following is true about non-uniform motion?
{
~ speed is always constant
~ cannot be measured
= distance covered can vary over time
~ only occurs in vehicles
}

If a truck covers 60 meters in the first minute and 80 meters in the next, it is
{
~ Not moving
~ Moving with a constant speed
= Moving with a varying speed
~ flying
}

Covering unequal distance in unit time is called
{
~ Uniform motion
= Non-uniform motion
~ velocity
~ periodic motion
}

If a cyclist covers 5 meters in the first second, 12 meters in the second, and 9 meters in the third, what is the average speed over these 3 seconds?
{
= 8 m/s
~ 9 m/s
~ 10 m/s
~ 11 m/s
}

If a cyclist covers 10 meters in the first second and 20 meters in the second, she is in
{
= Non-uniform motion
~ uniform motion
~ harmonic motion
~ Periodic motion
}

A truck covers 10 km every 15 minutes, it is in
{
= Uniform motion
~ Non-uniform
~ harmonic motion
~ periodic motion
}

//True or False

Rate of motion is a measure of how much the position of an object changes in unit time. {T}

The concept of non-uniform motion applies only to vehicles. {F}

In non-uniform motion, the distance covered in each second can change. {T}

If a truck covers 60 meters in the first minute and 80 meters in the next, it is moving at a constant speed. {F}

In non-uniform motion, the speed of an object only increases and never decreases. {F}

Average speed is calculated as total distance traveled divided by total time taken. {T}

A runner who covers the same distance every second is in non-uniform motion. {F}

Average speed can be calculated even if the object is in non-uniform motion. {T}

A ball rolling down a hill at varying speeds is an example of uniform motion. {F}

Speed of an object remains constant in uniform motion. {T}


//Match the Following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Average speed -> total distance by total time
=Uniform motion -> Constant speed
=SI unit -> m/s
=Non-uniform motion -> Varying distances over equal time
=At origin -> distance moved is zero
}
