Kinetic Energy Basics
The type of energy possessed by moving an object.
What is kinetic energy?
This law explains why a seatbelt saves lives in a car crash.
What is Newton's First Law (Law of Inertia)?
This law can be summarized by the equation F = ma.
What is Newton's Second Law?
When two objects interact, they exert these types of forces on each other.
What are equal and opposite?
The energy of motion is often converted to this type of energy due to friction.
What is thermal energy?
The formula used to calculate kinetic energy
What is KE = 1/2 * mass * velocity^2?
An object in motion stays in motion unless acted upon by this type of force.
What is an unbalanced force?
If the same force is applied to two objects of different mass, this happens to the one with less mass.
What is accelerates more?
The recoil of a gun is an example of this law.
What is Newton's Third Law?
When a pendulum swings, its kinetic energy changes into this at its highest point.
What is potential energy?
The factor has the greatest impact on increasing kinetic energy.
What is velocity?
An object at rest stays at rest unless acted on by this.
What is an external force?
This force causes a car to go when you press the accelerator.
What is the engine force?
When you push on a wall, the wall does this.
What is push back with equal force?
An object's kinetic energy will be at a maximum at this point of a swing.
What is the bottom?
Kinetic energy depends on these two properties of an object.
What are mass and velocity?
Newton's First Law is also known by this name.
What is the law of inertia?
If the net force on an object is zero, this will be its acceleration.
What is zero?
This physical quantity is conserved when ice skaters push off from one another.
What is momentum?
This term describes the transfer of energy from one form to another, like kinetic or potential.
What is energy transformation?
If the mass of an object doubles, this happens to its kinetic energy assuming constant velocity.
What is it doubles?
The tendency of an object to resist changes in its state of motion is called this.
What is inertia?
To calculate force, you need these two physical quantities.
What are mass and acceleration?
The action force of a rocket engine pushing gases out results in this reaction force.
What is the rocket moving in the opposite direction?
Kinetic energy is a form of this broader category of energy that includes both kinetic and potential energy.
What is mechanical energy?
