9.8 m/s
What is gravity?
This is measured in the unit Newtons
What is Force?
For every action there is an equal and opposite reaction
What is Newton's Third Law?
Energy in motion
What is kinetic energy?
The reason the ocean has tides
What is the moon?
An object has negative acceleration
This is how to calculate Force
What is Mass times Acceleration?
What is potential energy?
Motion under the influence of gravitational pull only
What is free fall?
The sum of all forces acting on an object
What is net force?
This is an object's tendency to resist changes in motion that affects it
What is inertia?
The unit of work
It depends on the height and mass of an object
What is gravitational potential energy?
Equal in size and opposite in direction
What is balanced forces?
An object with momentum must have these two things
What is mass and velocity?
Formula for gravitational potential energy
