What is force? |
A push or a pull that acts on an object. |
|
|
What is the overall force acting on an object after all the forces are combined?
|
net force
|
|
|
What is the force acting on an object when it is zero?
|
balanced force
|
|
|
What happens when an unbalanced force acts on an object?
|
The object accelerates.
|
|
|
What is friction?
|
A force that opposes the motion of objects that touch as they move past each other.
|
|
|
What is gravity?
|
A force that acts between any two masses.
|
|
|
Where does the force of gravity acts toward? |
the downward center of the earth
|
|
|
Gravity causes objects to accelerate downwards whereas air resistence acts...
|
in the direction opposite to to the motion and reduces acceleration.
|
|
|
Which newton law is this?
The state of motion of an object does not changes as long as the net forfce acting on an object is zero. |
1st law of motion
|
|
|
what is inertia?
|
the tendency of an object to resist change
|
|
|
what is mass
|
amount of matter |
|
|
what is newtons second law
|
acceleration=net force/mass
|
|
|
what is weight
|
the force of gravity acting on an object
|
|
|
what is formula for weight
|
weight= mass x valocity
|
|
|
what law is this: whenever one object exerts a force on a second object the second object exerts an equal and opposite force on the first object |
third law
|
|
|
Newton |
unit for force |
