A Phys

Front

radian

Back

angle (subtended at centre of circle) when arc length = radius

Front

centripetal acceleration

Back

acceleration perpendicular to velocity

Front

gravitational field

Back

where a mass experiences force

Front

gravitational potential at a point

Back

work done per unit mass to move mass from infinity to the point

Front

Newton’s law of gravitation.

Back

(gravitational) force is (directly) proportional to product of masses

(gravitational) force is (indirectly) proportional to square of separation

Front

relationship between gravitational potential and gravitational field strength

Back

(gravitational) field strength equals (gravitational) potential gradient

Front

line of gravitational force

Back

direction of force on a (small test) mass

path in which a (small test) mass will move

Front

internal energy of an ideal gas

Back

total kinetic energy associated with random motion of molecules

plus total potential energy (of molecules) but potential energy is zero

Front

internal energy of a system

Back

sum of potential energy and kinetic energy (of particles)

(total) energy of random motion of particles

Front

ideal gas

Back

(gas that obeys) pV  T (for all values of p,V and T)

where T is thermodynamic temperature
