Physics Final Review Day 1

Speed is:

• calculated by dividing the distance traveled by the time taken.
• zero for objects at rest.
• a measure of how quickly an object gets from one place to another.
• All of the above

Variables like velocity and acceleration that have both size and direction are called:

• vectors.
• dependent.
• axes.
• independent.

From home, you walk 6 blocks east and then walk 4 blocks west. Your distance from home is:

• 2 blocks.
• 4 blocks.
• 6 blocks.
• 10 blocks.

What is the speed of a jet plane that travels 3,000 meters in 10 seconds?

• 30 m/s
• 300 m/s
• 3,000 m/s
• 30,000 m/s

A graph can be described as:

• a mathematical diagram.
• a scientific model.
• a way to show relationships between variables.
• All of the above

On this graph, the dependent variable is:

• distance.
• speed.
• acceleration.
• the slope of the speed vs. distance curve.

When constructing a graph, the x-axis is most closely related to:

• the dependent variable.
• the vertical axis.
• the independent variable.
• the slope.

Use the graph to predict the speed of the car when the car is at 30 cm.

• 200 cm/s

• 150 cm/s

• 180 cm/s

• 190 cm/s

Figure 4-1A The above graph is of the height of an avocado tree plotted against its age from the time it is planted to when it is 8 years old. What is the independent variable for the graph in Figure 4-1A?

• Height

• Age

• Type of tree

• There is no dependent variable

Figure 4-1A The above graph is of the height of an avocado tree plotted against its age from the time it is planted to when it is 8 years old. What type of relationship do the variables have in the graph in Figure 4-1A?

• Strong relationship
• Weak relationship
• relationship
• No relationship
