Choices: True or False. If velocity is zero then acceleration must be zero too. If speed is constant then acceleration is zero. If velocity is constant then speed must be constant too. If speed changes then velocity must change too. Object slows down if it's acceleration is negative. If speed is constant then velocity must be constant too.
