Eaplain the following concepts if you own words
displacement, velocity acceleration distance?
Answers
Answer:
Force : Force is a push or pull acting on an object.
Effect of force :
Fore can change the state of rest or motion of an object.
Force an change the shape or size of an object.
Force can increase or decrease the speed of motion.
Force can change direction of motion of ball changes
Example :
When we hit a ball with bat, the direction of motion of ball changes .
Work Done : Work is said to be done on an object when a force acts on it and objects moves through a distance.
Example :
Work is said to be done when we project a ball in air.
Distance : Distance is the path traversed by an object.
Displacement is the shortest path travelled by an object between source and destination in specified direction.
An athlete running in circular path has distance covered as 2πR and displacement as zero.
Velocity is the speed with direction.
Car moving with a speed of 40km/hr towards north direction.
Acceleration :
Rate of change of velocity
a=v-u/t
A train leaving a platform station has positive acceleration.
