physics help

i get why theres deceleration as it goes up, but why is there no deceleration as it goes across the platform?

im nwe to physics btw

depends on the friction right

if theres no friction its not going to decelerate going over a flat surface no?

[echo vault]

oh i see

yes theres no friction

so for motion maps do you still draw dots there to say theres no accleration/deceleration?

[sage ruin]

Im assuming the only force working here rn is Gravity
i.e downwards
So just think why the acceleration is there when going up, we know the only thing that can accelerate or decelerate u is Gravity
U'll get the answer urself why there is no force(acceleration) acting when moving horizontally

bro i guess on platform theres no friction and on the slope the component of mg along slope provides the decellaration
