Forces Flashcards
What is the speed of gravity
9.81 m/s2
What is braking distance
The length the car travels after the brakes are applied
What is braking force
The measure of break power
What is thinking distance
How far the car travels before the breaks are applied
What is the equation for velocity
V=u+at
What is inertial mass
The ratio of force to acceleration
What is the thermal store of energy
Hot things
What is the kinetic store of energy
Moving objects
What is the chemical store of energy
Inside chemical bonds
What is the gravitational potential energy store of energy
Any object of the floor
What is the mechanical pathway
When a force is involved in changing the store of energy
Give an example of something that is non-efficient
Humans
Give an example of something that is efficient
Energy efficient fridge
What is the work done equation
W=fs
What is the law of the conservation of energy
Energy cannot be destroyed or created
What is momentum
A property of a moving object which depends on the mass of the objects and how fast its moving
How do you calculate momentum
P=mv
P- momentum (kg.m/s)
M- mass (kg)
V- velocity(m/s)
What is newtons 2nd law
Force is directly proportional to acceleration
