Motion And Energy

Question 1

How do you calculate AVERAGE ACCELERATION?

Answer 1

(Final Speed- Initial Speed) / Time = Average acceleration

Question 2

How do you calculate FINAL SPEED?

Answer 2

Initial Speed + (Average Acceleration x Time Taken)= Final Speed

Question 3

What is NEWTON’S 1ST LAW?

Answer 3

• An object at rest will stay at rest unless acted upon by a force
• An object moving will continue to move at the same speed and in the same direction unless acted upon by an unbalanced fore

Question 4

What is NEWTON’S 2ND LAW?

Answer 4

An object will accelerate in the direction of an unbalanced force acting upon it. The size of this acceleration depends on the mass of the object and the size of the force acting on it.

Question 5

What is NEWTON’S 3RD LAW?

Answer 5

For every action force there is an equal opposite reaction force
