Physics 1.4 - 1.6

Question 1

Which axis is the velocity on in the velocity time graph?

Answer 1

The y axis

Question 2

Which axis is the time on in the velocity time graph

Answer 2

The x axis

Question 3

What does the area under the curve represent?

Answer 3

The area under the curve represents the distance traveled

Question 4

That does the curve indicate?

Answer 4

The curve indicates the acceleration

Question 5

What does a line with no gradient indicate in a velocity time graph

Answer 5

It indicates that there is no acceleration and is moving at a constant velocity

Question 6

What does a curved line indicate in a velocity time graph?

Answer 6

It indicates either an increasing or decreasing rate of acceleration

Question 7

What does a straight line with a negative gradient indicate in a velocity time graph?

Answer 7

It indicates a constant decceleration

Question 8

What is terminal velocity

Answer 8

Terminal velocity is a constant speed that a falling object eventually reaches when the air resistance and the forces downward are equal to eachother causing no resultant force. This means there is no acceleration

Question 9

What is density

Answer 9

Density is a measurement of how close or far apart the particles are in a substance

Question 10

What is the formula of a density

Answer 10

Density = Mass/Volume

Question 11

How can we use a eureka can

Answer 11

We can use it to measure the volume of both regular and irregular solids

Question 12

How can we get a more accurate measurement of volume?

Answer 12

We can use a larger volume of water and we can repeat the experiment a handful of times and get the mean of the result
