Terms in this set (15)
What force is opposing to a push or pull?
friction (opposing forces)
What force is opposing to friction?
push or pull (opposing forces)
What force is opposing to the weight of an object if it is sitting on a table?
normal force (opposing forces)
What force is opposing to normal force?
Force of gravity or weight (opposing forces)
If an object has a mass of 1 kg what does it weigh?
If an object on a table weighs 10 N what is the normal force pushing back?
The value of acceleration due to gravity is...
If there is a net force on an object...
the object will accelerate
If the net force on an object is zero...
the object will not accelerate
If someone pushes an object with a force of 10 N and friction is 6 N, what is the net force?
How does acceleration describe the motion of the object?
Velocity is changing
If velocity is zero or is constant the acceleration is...
How does the value of static friction compare to kinetic friction?
static friction is higher
Static friction is present when...
a force is applied on an object and it is stationary on a surface
Kinetic friction is present when...
an object is in motion on a surface
