Calculations of force, momentum, etc Flashcards
What is the force equation?
F= M X A
What is the momentum equation?
Momentum = M X V Kg X m/s
What is force?
A push or pull that alters or tends to alter the state of motion of the body. Measured in N, mass in kg, acceleration m/s/s
What is momentum?
Mass on the move
What is velocity?
The speed of a body in a. given direction
What happens if the mass or velocity increases for momentum
Momentum increases and ice versa.
What happens when a body is stationary for momentum?
If a. body is stationary, have 0 velocity and no momentum. only bodies that move have momentum
What is displacement?
The shortest straight line- between start and finish points
What is the velocity calculation?
Displacement divided by time taken (m divided by s)
What is acceleration?
rate of change in velocity
What is the acceleration equation?
(v2- final velocity- v1 initial velocity) divided (time taken)
What is weight?
The gravitational pull that experts on a body (N)
What is the weight calculation?
Mass X acceleration due to gravity
