acceleration due to gravity

Question 1

Always round things to 2 significant figures

Answer 1

ye

Question 2

what is the acceleration due to gravity? (when it goes downwards)

Answer 2

9.8 meters per second squared
when a ball goes down, it is POSITIVE 9.8 METERS PER SECOND DOWNWARDS (because gravity ALWAYS acts upon an object and goes downwards)

Question 3

What is acceleration due to gravity when an object goes up.

Answer 3

acceleration due to gravity in this scenario would be -9.8 meters per second squared, since it is going against gravity and thus moving up. gravity is positive when going downwards

Question 4

ALWAYS CONVERT KM AN HOUR IN A PHYSICS PROBLEM TO METERS PER SECOND

Answer 4

fr

Question 5

underline and analyse question to see if you’re finding a vector quantity or a scalar quantity. Determine by using units

Answer 5

mhm

Question 6

How do you find the angle or direction in a vector diagram?

Answer 6

You need to find the bearing of the resultant vector, which ALWAYS starts from north. You can find this by using trigonometry and such

Question 7

What does the law of conservation of energy state?

Answer 7

The law of conservation of energy states that energy cannot be created nor destroyed. It is transformed into other types of energy and transferred to different objects.

Question 8

In a vector diagram, from where do you find the true bearing?

Answer 8

You find the true bearing from the END OF YOUR DIAGRAM. WRITE WHERE YOU STARTED AND WHERE YOU ENDED AND FROM THE ENDED ANGLE, USE TRIG AND FIND BEARING
