When you pitch a ball why are you not so much a baseball pitcher as a baseball accelerator?
because the ball goes faster as it gets closer to the batter
because as you go through your wind up you are accelerating the ball so that it leaves your hand at its top speed
you get tired from throwing the ball
because the ball is already going at its top speed at the beginning of your wind up.
Imagine you are sitting at the window of a train. How can you describe the position and motion of the train outside the window?
The train outside the window is moving quickly away from my train and my train may or may not not be moving.
Neither train is moving.
The train outside my window is moving very fast in the same direction as my train is moving.

Why are there two units of time in the units for acceleration?
because the object is moving faster
because one belongs to the speed and one belongs to the observer

Wheelchairs that are used for rugby are built of materials that are heavier because
this makes the chair less massive so the rugby player can speed up quickly as possible and race
this makes the chair so that the rugby player can race and speed up quickly as possible
this makes the chair less expensive
the chair needs to be stable and stay upright
Wheelchairs that are used for racing are built of materials that are light and strong because
the chair needs to be stable and stay upright
this makes the chair less massive so the racer can speed up quickly as possible and race
this makes the chair more massive so the racer can speed up quickly as possible and race
this makes the chair less expensive

Scientists are modeling different ways a satellite and an asteroid might crash into each other. They used the same satellite in both crashes, but two different asteroids—a black one with more mass for Crash 1 and a gray one with less mass for Crash 2. Use the information from the diagram to answer. In which crash does the satellite experience a stronger force? How do you know?
It was the same force in both crashes; the asteroid changed speed by the same amount in each crash, so the force on the satellite was the same each time.
Crash 1; the force exerted by the black asteroid would have been stronger in this crash, so the force on the satellite would also have been stronger.
The diagram doesn’t tell you anything about the force on the satellite. It only gives information about the force on the asteroids.
There is no force on the satellite. In both crashes, only the asteroid experiences a force.
Eugene and Van were playing with toys in a swimming pool. They crashed a rubber duck into two toy boats: a blue boat with less mass and an orange boat with more mass. The rubber duck had the same mass in both crashes. Use the information in the diagram to answer. In which crash did the rubber duck experience a stronger force? How do you know?
The diagram doesn’t tell you anything about the force on the rubber duck. It only gives information about the force on the toy boats.
There is no force on the rubber duck. Only the toy boats experienced a force in those crashes.
The force was the same in both crashes. The toy boats changed speed by the same amount so that means the force on the rubber duck was the same in both crashes.
Crash 2; the force on the orange boat is stronger, so the force on the rubber duck is also stronger
Which best explains why we are able to accelerate forward when starting to run?
The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward.
As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
The foot not touching the ground propels the entire body as it swings forward.
Inertia is often called laziness of an object because
the more friction an object has the more inertia it has
The density an object has the more inertia it has
The more mass the object has the more inertia it has
The more acceleration the object the more inertia the object has
