Physics 1.10 - 1.12

Question 1

Please check on vector and scale diagrams separately

Answer 1

Ok

Question 2

What does newtons first law state

Answer 2

Newtons first law states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by a resultant force

Question 3

Can a resultant force change the direction of an object?

Answer 3

Yes

Question 4

What is newtons second law

Answer 4

Newtons second law states that the resultant force acting on an object is directly proportional to that objects acceleration

Question 5

What is newtons second law formula

Answer 5

f = ma

Question 6

What is the m in newtons second law and what is it measured in

Answer 6

The m is the mass and it’s measured in kg

Question 7

What is the a in newtons second law and what is it measured in

Answer 7

The a is the acceleration and it’s measured in m/s^2

Question 8

What is moment

Answer 8

Moment is the turning effect of a force applied

Question 9

How is moment measured

Answer 9

Moment is measured by multiplying the force applied by the perpendicular distance to the force

Question 10

What is moment measured in

Answer 10

Newton meters

Question 11

What is the moment formula

Answer 11

M = fd where f is the force measured in newtons and d is the perpendicular distance measured in meters

Question 12

What is the moment of a force that is 200N and perpendicular distance is 5 cm?

Answer 12

10 Newton Meters or 10NM
