Throw a stone straight up in the air. At its highest height what is its speed? Is it accelerating then?
NOPE
NOOOOOOOOOOOOO
Thanks, that was super helpful.
WHICH OF THESE LEVELS THE LARGERT AREA
When a stone is thrown straight up in the air, its speed at the highest height will be zero. This is because at the highest point, also known as the peak of its trajectory, the stone momentarily stops before falling back down due to the force of gravity.
At this point, the stone is indeed accelerating downwards, even though its speed is momentarily zero. Acceleration refers to any change in velocity, which includes both changes in speed and changes in direction. In the case of the stone thrown straight up, its velocity changes from positive (going up) to negative (going down) at the highest point, therefore experiencing acceleration due to gravity.
