Is motion relative ?

• Yes

• No

• I know but i don't remember now

• Don't Know

Distance traveled by a car in first 5 mins is the same as the distance it covers in next 5 mins which is same as the distance covered by it in next 5 mins. the car is executing

• Non- uniform motion

• Uniform Motion

• Uniform Circular Motion

• None of these

Acceleration is measured opposite to velocity then

• acceleration is taken as positive

• acceleration is taken as negative

• Both options

• None of these

The motion of an athlete moving in a circular path at constant speed is an example of

• uniform motion

• accelerated motion

• uniform circular motion

• straight line motion

Balanced forces do not change the state of motion of an object.

• True

• False

• None of these

• Don't Know

Frictional Force acts in the

• same direction as motion

• opposite direction of motion

• friction force is not real

• all of the above

More massive objects have less inertia

• True

• False

• None of these

• Mass and inertia are not related
