Linear Motion

Question 1

What is distance?

What is displacement?

Answer 1

Distance is how much ground is covered - one point to another

Displacement is how far you finished from the start position

Question 2

What is speed? How is it calculated?

Answer 2

Speed is moving from one point to another in the fastest possible time
Distance travelled / time taken

Question 3

What is velocity? How is it calculated?

Answer 3

Speed in a given direction

Displacement / time taken

Question 4

What is acceleration?
Types of acceleration
How is it calculated?

Answer 4

Rate at which the object changes with respect to time
+ acceleration - increase velocity
- acceleration - decrease velocity

Acceleration due to gravity - natural force that makes object go downwards at rate of -9.8m/s

Uniform acceleration - an object accelerates at a constant rate

Change in velocity / time

Question 5

What is instantaneous speed?

Answer 5

Speed of an object that is constantly changing

Question 6

What is linear motion?

Answer 6

The path of an object that travels in a straight or curved line
