Forces Flashcards
What is the resultant force
The overall force that has the same effect on the objects as all the individual forces acting together
Give 3 types of force
Weight
Magnetic
Electrostatic
The pull in the stretched in the stretched spring is a……
Tensile force, (tension)
What are the units for mass
Kg
What are the units for Force
N
What are the units for Weight
N
What are the units for moments
Nm
Friction always acts to …… motion
Oppose
Friction is usually a…… force, (slows down movement)
Retarding
Suggest two factors that might affect the size of the friction force
The texture of the surface
The speed of the object
How is the friction force affected by the mass being pulled
The more mass there is, results in a higher amount of friction
What is the equation that links weight, mass and gravity
Weight = mass x gravity
What is mass
The objects mass in Kg
How big is the force gravity
10N/ Kg
Moment =
force x perpendicular distance
