Don't Stop the Motion
What is Motion?
A change in the objects position over time
What is the formula for speed?
Speed= distance/time
What is a force?
A push or a pull
What is Newton's 1st law of motion?
An object in motion will stay in motion until acted upon by an unbalanced force
What is a balanced force mean?
The net force on an object is equal to zero
What is the difference between speed and velocity?
Velocity includes a direction
What is Friction?
a contact force that resists motion between two surfaces
What are the units for force?
Newtons (N)
Which scientists was known as the "father or classical physics" and is usually depicted with an apple
Isaac Newton
What units is energy measured in?
Joules (J)
Which factors affect KE?
mass and speed
What is the acceleration of gravity that acts on object on Earth?
9.8 m/s2
When does acceleration happen?
When an object speeds up, slows down, or changes direction
Which formula is used in Newton's 2nd Law?
F=ma
What are the units for acceleration?
m/s2
What is the formula for potential energy?
mgh
What is Kinetic Energy? What is its formula.
Energy of motion. KE= 1/2mv2
What is gravitational potential energy?
What is Newtons 3rd Law of Motion?
For every action there is an equal but opposite reaction
What is Inertia?
an objects tendency to resist a change in motion
What is Elastic Potential Energy?
energy stored in an object that can stretch or squish to its original shape
Which would fall first in a vacuum, a feather or a bowling ball?
Both would fall at the same rate
What is the law of conservation of energy?
What is the difference between displacement and distance?
distance is total path traveled and displacement is the change in position from start to finish
