When an object has a negative acceleration, it means that

• it is slowing down

• it is speeding up

• it is going at the same speed

When an object has a positive acceleration, it means that

• it is slowing down

• it is speeding up

• it is going at the same speed

Speed = distance / time. What is the speed of an object traveling 50 miles in 1 hour?

• 50 miles/hour

• 50 miles

• 50 hours

• 25 mph
