Planet x has 4 times the mass of earth and a radius of half that of earth, how many times larger is the acceleration due to gravity on planet x then on earth?

4 times the mass of Earth . . . multiplies Earth gravity by 4

1/2 of Earth's radius . . . multiplies Earth's gravity by 4

both changes . . . multiplies Earth gravity by (4 x 4) = 16

The acceleration of gravity on the surface of Planet-X is 16 TIMES that on the Earth's surface ... about 6.3 times what it is on Jupiter.

You could not walk around on Planet-X, and it's pretty likely that whatever contraption you landed in could not take off again.  You're stuck on Planet-X, living out the short remainder of your life just laying there like a heavy pancake and using all of your strength just trying to breathe.  It won't be pretty.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
