Which of these cars do you think is not accelerating? A car stopped at a curb
A car slowing down at a stop sign
A car speeding up to pass another car
A car turning a corner

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
