Energy Race Around The World French Guiana Answers with direction

1) negative acceleration, but positive velocity

if a ball is thrown up then velocity is positive upwards while acceleration is downwards negative

2) positive acceleration and positive velocity

if a car is moving towards positive direction with increasing speed due to which acceleration is also positive in it

3) positive acceleration, but negative velocity

if a car is moving towards negative direction and car apply brakes due to which it will slow down then its acceleration must be positive

4) negative acceleration and negative velocity

when a ball is falling downwards under the influence of gravity then velocity and acceleration both are positive

5) positive velocity and no acceleration

if an object is moving with uniform speed towards positive x direction without any acceleration or force
