It contains all the contents I wanted!! God bless u😘😘😘😘

NIcely explained !! Thank you

Love your accent!

WhT would ve velocity vs position graph for ground to ground motion

superp explaination

Thanku

Basically in graph system we are comparing velocity with acceleration and distance by velocity??

Bhai just assume that in straight line average speed =Average velocity.

how would a graph of time and position look like for a falling body if up was negative and down was positif

Slope is velocity. As the object moves up, it moves in the negative direction and the slope decreases, so it’s a downward curve. As it comes down, it should move upward with increasing slope, so it’s a upward curve. The graph of up & down motion is shaped like a bowl. I hope that helps.

difficult explaination how can we represent when a body is thrown from the ground

You didn't tell the acceleration time graph of a free falling body

acceleration is constant. so it is a horizontal line because it doesn't change with time.

@@ylabarbera will that horizontal line break at the time when that freely falling body touches the ground ,i.e. will the graph be discontinuous at the time when the body touches ground please tell e.g. for a ball which is falling freely from a height and touches the ground and then rebounds to the same height please tellll

Very nice

Do free falling objects possess constant velocity?

@dianalabarbera201

No. All free falling objects accelerate downward, due to gravity which pulls everything down. The acceleration is has a constant magnitude (value) in downward direction but the speed is increasing in the downward direction.

Are a using NCERT or HC Verma

Explicit explanation

Why are you considering acceleration as -'ve 9.8m/s^2 for a free fall Acceleration is always +'ve and velocity always increases when an object freely falls downwards!!!!

acceleration is downward. If upward is defined as positive, as we usually do, then acceleration is negative. the direction of acceleration is defined as the following: if an object speeds up, then acceleration and velocity are in the same direction. for example, if the object is moving in the positive direction, then acceleration is positive; if the object is moving in the negative direction, then the acceleration is negative. So, if I define downward as negative, then acceleration is negative. However, if I define downward as positive, then acceleration is positive.
