Forces
What is a force?
a push or pull on an object that can cause it to move, change its speed, direction, or even its shape
What is unbalanced forces
a situation where the net force acting on an object is not zero
What is friction
force that resists the sliding or rolling of one solid object over another
What is "Push"
to press against something with steady force in or as if in order to impel
What are balanced forces
forces that are equal in magnitude and opposite in direction, resulting in no net force and no change in an object's motion
What can make Friction
microscopic roughness of surfaces, where irregularities catch and impede motion
What is "Pull"
to use force in drawing, dragging, or tugging
Is push a balanced force
No push is not a balanced force
What is friction made of
a force that arises from the interaction between surfaces in contact
What is Gravity
an invisible force that pulls objects toward each other
Is Pull a balanced force
No pull isn't a balanced force
What increases friction
making surfaces rougher, increasing the force pressing them together, and using materials that increase friction
What are the 7 types of forces
gravitational, normal, friction, applied, air resistance, tension, and spring
What can a unbalanced force do
cause a change in an object's motion
