Unit 03 - Acceleration

4

The velocity-time graph for a two-stage rocket is shown below. Use the graph and your understanding of slope to drag and drop the acceleration of the rocket during the listed time intervals.

null

The acceleration of the object from t=0 to t=1 is .

The acceleration of the object from t=1 to t=4 is .

The acceleration of the object from t=4 to t=12 is .

What is the graphical interpretation of the motion of the car?

0

Explain the velocity of a thrown object. Your response should address the velocity change of the rise, the peak, and the fall.

0

Acceleration due to gravity ...

is always in the negative (downward direction)

is the same on Earth as it is on the Moon

changes when an object moves

can change based on your location on Earth

always pulls you towards the center of the Earth

remains about -9.8 m/s/s on Earth at all times

What is the landing speed?

Unit 04 - Forces and Momentum

2

A 2-kg object is moving horizontally with a speed of 4 m/s.
How much net force is required to keep the object moving at this speed and in this direction?

4 N

0 N

12 N

8 N

4

One Newton of Force is equal to ______________

6

A thrown desk is moving upward and leftward towards the peak of its trajectory. Ignore the air resistance. (Grading on forces and magnitudes)

4

Why does constant velocity indicate NO net force?

constant velocity means no acceleration, and for there to be a net force there must be acceleration

net forces are connected to velocity, not acceleration

constant velocity means that there is acceleration, and therefore means that there is no net force

for something to be moving at a constant velocity means there must be a force acting upon it somewhere (Mr. Fischers Example of the Laptop Case)

2

Doubling of the net force results in a of the acceleration (if force is held constant).

2

Explain what is meant by 'terminal velocity.'

Terminal velocity is when fgrav and net force become equal and then there ceases to be any fair on the object.

Terminal velocity is when net force and fair become equal and then there ceases to be any fgrav on the object.

Terminal velocity is when fgrav and fair become equal and then there ceases to be any net force or acceleration on the object.

Terminal velocity is when fair becomes greater than fgrav and then the net force or acceleration on the object increases.

4

The more momentum that an object has, the harder that it is to stop. Thus, it would require a or both to bring such an object to a halt.
