College Physics 1

Not that your opinion will make the final decision, but what kind of test would you rather have?

• Multiple Choice Only - math questions will be asked in in multiple choice format
• Free Response Only - separate problems each covering a single concept
  
• One long free response problem covering all the topics
• You will be thoroughly reviewd, no matter which kind of test we have. Don't pick this answer

When a car rounds a corner at a constant speed, its acceleration is zero.

• true
• false

A ball is thrown upwards and caught when it comes back down. In the absence of air resistance, the speed of the ball when caught would be 

• less than the speed it had when thrown upwards.
• more than the speed it had when thrown upwards.
• the same as the speed it had when thrown upwards.

Suppose an object is in free fall. Each second the object falls 

• the same distance as in the second before.
• a larger distance than in the second before.
• with the same instantaneous speed.
• with the same average speed.

A ball tossed vertically upward rises, reaches its highest point, and then falls back to its starting point. During this time the acceleration of the ball is always 

• in the direction of motion
• opposite its velocity
• directed downward
• directed upward

The horizontal component of a projectile's velocity is:

• constant 
• a constant acceleration
• always -9.8 m/s² down

When a projectile is at the highest point of its path, the vertical velocity is:

• Constant
• Always -9.8 m/s²
• Zero
