Forces and Motion Flashcards
On Earth, how much is 250N (in kg)?
25kg
What is the definition of balanced (forces)?
The forces on both directions are equal
What is the definition of unbalanced (forces)?
The forces on both directions are unequal
What is the definition of the resultant force?
The force acting on an object after all cancellations are made
What is the resultant force and its direction of : <-267N # 211->
<-56N
When forces are balanced…
an object will either remain stationary or move ate a constant speed
When forces are unbalanced…
an object will either speed up or slow down
When an object is stationary on the ground, which 2 forces are acting upon it?
Weight and reactive force/reaction force/contact force
What is the reactive force/reaction force/contact force?
The force acting against weight and tries to balance the forces of itself and weight
What happens if the force from weight is greater than reactive force/reaction force/contact force?
The surface on which the object is on will break
On Earth, how much is 54kg (in Newtons)?
540N
What is the conversion between mass (kg) to weight (N) on Earth?
Mass x 10 = Weight
A force can change an object’s…
Speed, direction, shape, and volume
What is weight?
The force pulling an object towards the ground/a surface.
What is mass?
The amount of stuff/matter inside an object.
