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 slanted surface, because of decreased friction

• the ball on the slanted surface, because of increased gravity

• the ball on the flat surface, because of decreased gravity

• the ball on the flat surface, because of increased friction

Which best represents the relationship between force and the mass of an object?

• The greater the force, the smaller the object.

• The smaller the force, the smaller the object.

• The force on an object determines what density it has.

• The greater the mass of an object, the greater the force needed to move it.
