A force has both what?
A force is a vector quantity because it has both magnitude and direction.
What is a device that does work with only one movement and changes the size and direction of the force?
It is an effort machine
Why is force a vector of quantity?
it has magnitude and direction
A force vector describes what two things about a force?
magnitude and direction more accurate magnitude and sence.
A device that changes the size or direction of force used to do work?
Those kinds of devices are called machines.
What is any device which transfers or changes the direction of a force?
Machine
A force has both what?
A force is a vector quantity because it has both magnitude and direction.
What does every force have?
A magnitude, direction and sense of direction. it has an equal and opposite force too. eather way it also has a magnitude, direction and sense of direction.
When a force on an object increases how does the object acceleration change?
Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.
What is a magnitude of force?
The magnitude of a force is its 'size' or 'strength', regardless of its direction.
What are the all component of muscular force?
1. Magnitude 2. Direction 3. Application of force 4. Line of force
What is the definition of a simple machine?
a simple machine is a mechanical device
What does a force have?
A force has both magnitude and direction
Is direction a force?
I don't know but Force has Magnitude and Direction (and it also has size).
The length of a vector arrow represents its?
The direction of the arrow represents the direction of the force; the length of the arrow is proportional to the magnitude of the force.
What is a device that does work with only one movement and changes the size and direction of the force?
It is an effort machine
10 examples of law of acceleration?
-- A car accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the car. -- A stone accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the stone. -- A Frisbee accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the Frisbee. -- A baseball accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the baseball. -- A dog accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the dog. -- A book accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the book. -- A canoe accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the canoe. -- An airplane accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the airplane. -- A planet accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the planet. -- A cow accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the cow.
