is the vector sum of all the forces that act upon an object.
net force
tates that an object at rest will remain at rest and an object in motion will stay in motion unless it is acted on by an unbalanced force.
Newton’s first law of motion
describes how force and mass affect acceleration and shows that there is a direct relationship between force and acceleration.
Newton's second law
When two forces acting on an object are not equal in size, we say that they are...
unbalanced forces.
The change in the motion of an object depends upon:
the size of the net force. -the direction of the net force.
is the force of gravity acting upon that object.
weight
The greater the mass of an object, the less it will.............when a given force is applied.
accelerate
fundamental property of all matter
mass
is a measure of the speed and direction of motion,
velcity
Two factors that affect the acceleration of an object are ...
the net force acting on the object and the object’s mass.
