Question 1

what is the correlation between acceleration and resultant force

Answer 1

the greater the resultant force on an object, the greater the acceleration

Question 2

what is the equation for resultant force

Answer 2

resultant force=mass x acceleration

Question 3

how do you work out the acceleration on a velocity time graph

Answer 3

the gradient of the live

Question 4

what is newtons second law

Answer 4

the acceleration of an object is proportional to the resultant force and inversely proportional to the mass of an object

Question 5

what is an inertia

Answer 5

the tendancy for an object to stay at rest or continue at constant velocity

Question 6

how do you find inertial mass

Answer 6

inertial mass=force/acceleration

Question 7

why does an object accelerate

Answer 7

the resultant force goes in the same direction as its velocity

Question 8

why does an object decelerate

Answer 8

the resultant force is in an opposite direction to its velocity

Question 9

what is the equation for weight

Answer 9

weight = mass x gravitational field strength
