Scalar Quantities has no direction.
How many dynes are there in a newton?
10,000
100,000
1,000
Vector quantities has no direction.
Both vector and scalar quantities has magnitude.
When is an object most stable?
when the location of the center of gravity is near the support base
when the center of gravity is at the center of the object
When do you consider an object unstable?
When the center of gravity is at the center of the object
When it easily topples over
When the center of gravity is far from the center
When the center of gravity is lowered when given a tap.
Torque is a concurrent force
Torque isn't a force
Define torque.
Torque is a force that causes a rotation on objects.
A physical quantity that causes rotation.
How do you compute for the applied force (torque)
Multiply the other two forces
Add the other two forces
What is the direction of a positive torque?
Counterclockwise
Clockwise
What is the relationship between the radius and the torque?
Direct Proportion
Direct Square Proportion
Inverse Proportion
How do you compute for the amount of Torque produced by a force?
Torque=force*radius
Torque=radius/force
Contact forces:
Electric force
Buoyant force
friction
Magnetic force
Normal force
Applied force
Tension
Force of Gravity
Always directed upward:
gravity
Always parallel to the surfaces in contact:
Gravity
In any direction:
Force of attraction between 2 objects
Always perpendicular to the stable surface.
Applied Force
Objects that are in equilibrium include:
constant speed
constant velocity
at rest
constant acceleration
An object having the length of 5m has its center of gravity at 3 meters. What would happen if the object was cut on its center of gravity?
The two halves would weigh the same
The longer one would have the greater mass
The shorter half would have the greater mass
