Two identical balls are pushed with the same force. One ball is pushed along a flat surface and the other ball is pushed down a slanted surface. Which ball will travel faster and why?

• the ball on the flat surface, because of increased friction
• the ball on the flat surface, because of decreased gravity
• the ball on the slanted surface, because of increased gravity
• the ball on the slanted surface, because of decreased friction
