Forces Flashcards
What is a vector
Magnitude and direction
What is a scaler
Magnitude
What is velocity measured in
Ms-1
What is acceleration measured in
Ms2
What is final speed and initial speed measured in
Ms-1
What is acceleration
The change in speed per second
How do we measure distance in a speed time graph
Split into sections find area of all sections and add them all up
What do forces do
Change shape speed direction
What are balanced forces
They are equal in size and opposite in direction
What is neutrons first law
Remain at rest or constant speed unless acted upon by unbalanced force
What does a bigger unbalanced force do to acceleration
Makes the acceleration bigger
What is newtons 2ns law
The acceleration varies directly
With unbalanced forces and inversely
With mass
What is mass measured in
Kg
What is force measured in
Newtons
What does a smaller mass
Do to acceleration
Has a faster acceleration
