What is false.
If the net force acting on an object is 0, then the object has a _________ force.
A car and a large truck are rolling down a hill. Which will take more force to stop it?
The truck because it has more mass
What are the 2 factors that affect kinetic energy?
Mass and speed

System A-Two players colliding, System B-A player getting hit by a ball, System C-A player falling to the ground
Which system has the LEAST amount of total kinetic energy? Which system would have the MOST Kinetic energy and force?
LEAST-System C because the ground does not have kinetic energy (energy of motion)
MOST-System A both players have Kinetic energy and the players have more mass so they will exert more force
