1.
In the Galilean transformation, the time coordinate satisfies
t′ = t − vx/c2
t′ = t
t′ = t/v
t′ = vt
2.
A cyclist at 6 m s−1 is overtaken by a car at 16 m s−1 in the same direction. The car's velocity relative to the cyclist is
6 m s−1
16 m s−1
22 m s−1
10 m s−1
3.
Which quantity is the same in all inertial frames under Galilean relativity?
Acceleration
Velocity
Kinetic energy
Position
4.
A frame S′ moves at 12 m s−1 along +x relative to S. An object has velocity −5 m s−1 in S. Its velocity in S′ is
+17 m s−1
+7 m s−1
−17 m s−1
−7 m s−1
5.
Why can the Galilean transformations not be exact?
They give light different speeds for different observers
They ignore mass
They need three dimensions
They predict gravity is constant
6.
The principle of Galilean relativity states that
velocities are frame independent
time depends on speed
only one frame is at rest
mechanics experiments cannot reveal uniform motion
