SQA Advanced Higher Physics Area 1 Rotational Motion and Astrophysics overview quiz quiz

It is the first derivative of displacement with time

It is the second derivative of displacement with time

It is the integral of displacement with time

It equals displacement divided by time squared

They are only valid at low speeds

They are derived by integrating a constant acceleration

They ignore air resistance

They only work for vertical motion

The final velocity

The maximum displacement

The initial conditions

The average acceleration

F = ma only

F = m v squared over r

F = mgh

F = I times alpha

v = r omega

v = omega / r

v = r / omega

v = r squared omega

Only its mass

Only its angular velocity

Its mass and how that mass is distributed about the axis

Only its radius

F = ma

tau = I alpha

L = I omega

E = half I omega squared

They spin more slowly because mass moves inward

They spin faster because their moment of inertia decreases

Their angular momentum increases

Nothing changes

Because mass is always positive

Because gravity is attractive and the zero of potential is at infinity

Because g decreases with height

Because of a sign convention with no physical meaning

the square root of GM over r

the square root of 2GM over r

2GM over r

GM over r squared

T is proportional to r

T squared is proportional to r cubed

T cubed is proportional to r squared

T is proportional to r squared

Mass and energy are equivalent

Locally, a uniform gravitational field is indistinguishable from a constant acceleration of the frame

All inertial frames measure the same speed of light

Energy can be created from nothing in a strong field

An invisible force field

The curvature of spacetime by mass and energy

The exchange of photons

Magnetic attraction between masses

r = GM / c squared

r = 2GM / c squared

r = 2GM / c

r = GM squared / c

It is independent of distance

It falls off as one over distance

It falls off as one over distance squared

It increases with distance

On a horizontal band at the bottom

On a diagonal band from hot and luminous to cool and dim

Only at the cool, luminous corner

Scattered with no pattern

Nuclear fission of heavy elements

Nuclear fusion of hydrogen into helium

Chemical burning of gases

Gravitational collapse alone
