What does newtons first law state
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
Can a resultant force change the direction of an object?
Yes
What is newtons second law
Newtons second law states that the resultant force acting on an object is directly proportional to that objects acceleration
What is newtons second law formula
f = ma
What is the m in newtons second law and what is it measured in
The m is the mass and it’s measured in kg
What is the a in newtons second law and what is it measured in
The a is the acceleration and it’s measured in m/s^2
What is moment
Moment is the turning effect of a force applied
How is moment measured
Moment is measured by multiplying the force applied by the perpendicular distance to the force
What is moment measured in
Newton meters
What is the moment formula
M = fd where f is the force measured in newtons and d is the perpendicular distance measured in meters
What is the moment of a force that is 200N and perpendicular distance is 5 cm?
10 Newton Meters or 10NM
