What would you be measuring if you had the object's speed and direction

• momentum

• velocity

• force

• weight

What is speed?

• Speed is how far something travels in one hour.

A student reads his paper on friction to the class. Which statement should he include in his paper if he wants to present accurate information? 

• Friction increases mechanical advantage
• Friction opposes the direction of movement. 
• Friction makes movement of an object easier.
• Friction reduces the amount of work used to move an object. 

 If an unbalanced force acts on a stationary object, the object will:.

• remain stationary
• move away from the force
• accelerate in the direction of the force
• accelerate in the opposite direction of the force
