What do we call velocity that does not change? A 100

It is called constant velocity. A 100

Why is velocity is a vector quantity? A 200

Velocity has both magnitude and direction. A 200

What causes a change in acceleration? A 300

A change in magnitude or direction. A 300

What are the common SI units of acceleration? A 400

m/s 2 (meters per second per second) A 400

If the sign of velocity is negative, and the sign on acceleration is positive, is the object slowing or increasing its speed? A 500

It is slowing down. A 500

How is a scalar different from a vector quantity? B 100

A vector quantity has both magnitude and direction, while a scalar has only magnitude. B 100

What is the term refers to the total length of an object’s movement? B 200

Distance B 200

What results from the addition of vectors? B 300

A resultant. B 300

What term is refers to the shortest distance between initial and final positions? B 400

Displacement B 400

Which of these is not a vector quantity? momentum, centripetal force, mass, or work B 500

Mass B 500

What scientist experimented with and conducted “thought experiments” on falling bodies. C 100

Galileo C 100

Two object of different masses, falling near the earth’s surface in a vacuum, should accelerate to earth at what rate? C 200

Both should acceleration to Earth at approximately 9.8 m/s 2 C 200

What factors could affect the rate an object accelerates through the earth’s atmosphere? C 300

Air Resistance and shape of the object. C 300

DAILY DOUBLE C 400 DAILY DOUBLE Don’t Place A Wager

What is the relationship between time, g, and the distance fallen by a freely- falling object? C 400

Distance increases proportionally with the square of time (distance fallen = ½ gt 2 ) C 400

What are astronauts on the International Space Station weightless? C 500

They are in a constant state of free fall because they are in orbit. C 500

If a plane flying 200 miles/hr drops a package, neglecting air resistance, where will the plane be in relation to the package when it hits the ground? D 100

Directly over the package. D 100

Neglecting air resistance, what is the only force that acts on a projectile once it is launched? D 200

Gravity D 200

One a projectile is launched, what allows it to continue its forward motion before it hits the ground? D 300

Its own inertia. D 300

Neglecting air resistance, the path of a projectile has what shape? D 400

What is parabolic? D 400

Which of the following demonstrates projectile motion? A punted football, a cannon ball shot from a cannon, a baseball thrown straight up into the air, a water droplet from a sprinkler head. D 500

The baseball thrown straight up into the air. D 500

What is Newton’s First law of motion? E 100

A body naturally tends to continue in whatever state of motion or rest and tends to resist any changes. An object at rest tends to stay at rest. An object in motion tends to stay in motion (unless an unbalanced force acts on it). E 100

What property of matter refers to resistance to a change in motion? E 200

Inertia E 200

What equation can represent Newton’s second law of motion? E 300

F = ma E 300

What is the relationship between force and acceleration according to Newton’s second law? E 400

They are directly proportional (The larger the force, the greater the acceleration.) E 400

What is Newton’s third law or Motion? E 500

When an object exerts a force on a second object, the second objects exerts a force on the first that is equal in size and in the opposite direction. (“To every action, there is an equal and opposite reaction.”) E 500

Where on the graph below is there constant velocity? F 100

(b) F 100

A Newton-meter is equivalent to what unit of work or energy? F 200

The Joule F 200

Power may be defined by what relationship? F 300

Power = work/time (the rate at which work is done) F 300

What is the unit of Power? F 400

The Watt F 400

What law states that energy is not created or destroyed, but converted from one form to another? F 500

The Law of Conservation of Energy. F 500

How does a simple machine make work easier? Click on screen to continue

A simple machine can increase the amount of effort force applied to the machine. It can do this by increasing the distance that the effort force is applied (such as using a long lever to pry a heavy object). Click on screen to continue
