Chapter 2: (1 & 2) Linear Motion

Question 1

What is linear motion?

Answer 1

The movement of an object in a straight line.

Question 2

What is distance?

Answer 2

Length of route covered by an object.

Question 3

What is displacement?

Answer 3

Shortest distance between the initial and final position in a specific direction.

Question 4

What is the definition of speed and its formula?

Answer 4

The rate of change of distance travelled; v = d/t

Question 5

What is the definition of velocity and its formula?

Answer 5

The rate of change of displacement; v = s/t

Question 6

What is the definition of acceleration and its formula?

Answer 6

The rate of change of velocity; a= (v-u)/t

Question 7

What is a ticker timer?

Answer 7

A mechanical device used to measure the time taken by an object to move between two points.

Question 8

How do you find the velocity in the displacement time graph?

Answer 8

By calculating the gradient of the graph.

Question 9

How do you find the acceleration in the velocity time graph?

Answer 9

By calculating the gradient of the graph.

Question 10

How do you find the displacement in the velocity time graph?

Answer 10

By calculating the area under the graph.
