Students measure the speed of a marble rolling down a ramp. The chart contains the collected data. Which graph best represents this data?
Which statement accurately reflects the relationship between speed and velocity?
Speed and velocity are the same.
Speed and velocity are not related.
Velocity is speed plus direction.
Speed is velocity plus direction.
A roller coaster car travels up a hill until it reaches the top, slowly goes over, and speeds down the hill and through the rest of the roller coaster. At the end, the brakes quickly stop the car, and riders appear to continue moving forward. Which of Newton's Laws of motion best applies to the riders of the roller coaster?
Newton's Law of Acceleration
Newton's Law of Inertia
Newton's Law of Action-Reaction
Newton's Law of Force and Acceleration

A student exerts a force on the wall. What is the net force acting on the wall?
20 N to the right
20 N to the left
0 N, they are balanced forces.
a wall can't exert a force.
During photosynthesis, plants convert energy from solar energy to what type of energy?

Boxes A and B each weigh 22.68 kilograms. A student applies 20 N of force to Box A and moves it 6 meters. Using an inclined plane, the student applies 8 N of force to Box B and moves it 15 meters. Which box required more work to move?
**Hint: use formula for work**
Box A required more work because more force was applied.
Box B required more work because it moved a greater distance.
Both Boxes required the same amount of work because using an inclined plane increases the distance.
Both Boxes required the same amount of work because they were both moved by the same person.
At which point would the ball have maximum potential energy?
Point W
Point X
Point Y
Point Z

A student lists examples of speed, velocity, and acceleration in a table. Which example completes the table?
Ant walks the perimeter of a window.
Easterly wind blows at a rate of 35 km/h
Swimmer completes a lap at a rate of 2 m/s
Truck stops at the station in town.
The diagram shows a book that slides from left to right across a tabletop. Why are the forces balanced upward and downward, but not balanced left and right?
The unbalanced force is directed in the same direction as the book's motion and will cause it to decrease its speed.
The unbalanced force is directed in the opposite direction of the book's motion and will cause it to decrease speed.
The unbalanced force is directed in the same direction as the book's motion and will cause it to increase its speed.
The unbalanced force is directed in the opposite direction of the book's motion and will cause it to increase speed.
A police officer writes speeding tickets to drivers of four cars for speeding on the highway with a posted speed limit of 70 km/h. The distances and times traveled by the cars are shown in the table. All four drivers claim they were not speeding. Which driver has a valid claim?
The driver of the red car.
The driver of the blue car.
The driver of the green car.
The driver of the black car.
The diagram shows the motion of a pitcher. Which statement best describes the energy of the pitcher?
Hospitals use gasoline-powered generators during power outages to keep lifesaving equipment working. What energy transformations take place within a generator?
Chemical energy to electrical
Chemical energy to mechanical energy to electrical energy
Mechanical energy to chemical energy to electrical energy
Electrical energy to mechanical energy to chemical energy
A propulsive force, called a thrust, is used to launch a rocket. A rocket must have a high thrust to mass ratio to reduce drag. A rocket increases speed as the propulsive force increases. Lift-off occurs because the propulsion force is able to push the rocket off the launch pad. Because of the acceleration imparted, the force is able to overcome the tendency of the rocket to stay on the launch pad. Which of Newton's Laws can be applied to a rocket launch?
1
1 and 2
1 and 3
all of the above
A family flew from their hometown to a vacation destination. The speed of the jumbo jet from takeoff to landing is graphed. How would you describe the speed during the flight?
A 747 airliner travels 91.4 km in 0.1 hour. What is the average speed of the airliner?
91.4 km/h
914 km/h
9.14 km/h
0.914 km/h
