Physics Review

Which of the following correctly describes the motion?

• an object at rest

• an object at constant speed

• an object accelerating

• an object with changing velocity

If the same force is applied, which car will accelerate more quickly?

• a car with a smaller mass

• a car with a bigger mass

How are speed and velocity different?

• Speed included direction.

• Speed indicates momentum.

• Velocity includes momentum.

• Velocity includes direction.

What is the speed of an object that travels 20 meters in 4 seconds?

• 80 m/s
• 0.2 m/s
• 5 m/s
• 24 m/s

What Newtons law does this picture represent

• Newtons 2nd law 
• Law of gravity 
• Newtons 1st law
• Newtons 5th law

The roller coaster has the most kinetic energy at position-

• W
• X
• Y
• Z

Without any force to change it, an object at rest stays at rest and an object in motion stays in motion

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

Energy can neither be created nor destroyed, it just changes form.

• Law of Energy
• Law of Conservation of Energy
• Law of Constant Energy
• Law of Energy Not Losey

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy? 

• Both the potential energy and kinetic energy decrease
• The potential energy decreases while the kinetic energy increases 
• The kinetic energy decreases while the potential energy increases 
• Bothe the potential energy and kinetic energy increase 

This is an example of a _______ circuit

• open
• series
• parallel
• square
