A hiker’s velocity begins at 1.8 m/s uphill and changes to 1.5 m/s uphill. How do you know that the hiker has a negative acceleration?

• His direction changed.
• His direction was unchanged.
• His speed increased.
• His speed decreased.

A crumpled piece of paper hits the ground before a flat sheet of paper because

• the acceleration of gravity is greater on the  crumpled paper.
• there is more air resistance against the flat paper.
• the crumpled paper is more massive
• the crumpled paper is less massive.

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
