Unit 1
A man walks 9 steps forward from his original position to get his box. He then walks 3 steps back to get his ball. What is his displacement
what is 6 steps
If your applying a force of 50N forward what direction is the friction.
backward
If a ball is at the top of a hill 100m in the air what is the kinetic energy
KE=0
What type of matter has a definite volume but not a definite shape.
liquid
what do planets orbit
the sun
The ball rolls 3m back what is the displacement
what is -3m
If f1 was 20N forward and f2 is 10N backward what is the net force.
10N forward
If the ball is dropped from 20m in the air when is the kinetic energy at its max
right before it hits the ground.
what type of matter has neither definite shape nor volume.
gas.
The Northern Hemisphere is pointed toward the Sun what type of season is this
summer
A man runs a lap and starts at 50m and at 50m stops at the same place what is his displacement
what is the definition of a force
a push or pull on an object.
If a ball is rolling down a hill at 50N what is the potential energy
what type of particles do solids have
close compact particles.
The Northern Hemisphere is pointed away from the Sun
winter
