what forces are when the net force on an object is not zero
unbalanced forces
a push or pull
force
a pulling force exerted on a material when it is stretched
tension force
a boy pulling a wagon is an example of this type of force
contact force
contact force that acts to resist sliding between two touching surfaces
friction
what forces are when the net force on an object is zero
balanced forces
the combination of all the forces acting on an object
net force
If forces are balanced then the net force would be...
balanced
an attractive force between all objects that have mass
gravity
forces one object exerts on another when they are not touching
noncontact force
law that states: all objects are attracted to each other and the force of attraction depends upon their masses and the distance between them
law of universal gravitation
An object that resists having its motion change would be which of Newton's laws
Newton's 1st Law of Motion
the gravitational force exerted on an object
weight
law that states: if the net force on an object is zero, an object at rest remains at rest, or, if the object is moving, it continues to move in a straight line with a constant speed
Newton's 1st Law of Motion
force exerted by a material when it is stretched or compressed
elastic force
What are two factors that influence the acceleration of an object
net force and mass
Force exerted only when two objects are touching
contact force
a pushing force exerted on a material when it is squeezed
compression force
a force exerted by an object that is perpendicular to the surface of the object
normal force
Define the force that would cause you to have to pedal harder on gravel than on cement
Friction
