1.The numerical ratio of displacement to distance for a moving object is:
a)always less than 1
b)always equal to 1
c)always grater than 1
d)equal to or less than 1
explain too...
Under what condition is the magnitude of average velocity of an object equal to it's average speed?
give some examples of accelerated motion in everyday life
A ball is dropped on the floor from the height of 10m. It rebounds to a height of 2.5m. If the ball is in contact with the floor for 0.01 seconds, what is the average acceleration during contact ?
What is To and Fro Motion? Explain with examples.
Derive the equation :
EXPLAIN WHETHER THE WALLS OF A CLASSROOM ARE AT REST OR IN MOTION?
A train starting from rest attains a velocity of 72 km/h in 5 minutes. Assuming that the acceeration is uniform. Find the acceleration and the distance traveed by the train for attaining this velocity.
draw a velocity versus time graph of a stone thrown vertically upwards with a velocity v and then coming downwards after attaining the maximum height.
Difference between mass and weight
a body can have zero average velocity but not zero average speed . justify
what are the similarities between distance and displacement ?
A body covers 4m in 3rd second and 12m in 5th second. If the motion is uniformly accelerated, how far will it travel in the next 3 seconds?
An electric train is moving with a velocity of 120 km/ hr. How much distance will it move in 30 seconds.
