Energy conversion
What is Kinetic Energy?
The energy of an object because of its motion.
What is gravity?
Force of attraction between things that have a mass is called gravity.
What is force?
Push or a pull on an object that can change its motion or shape.
The energy stored in an object because of its state (can also be called stored energy)
Who was the first person to observe effects of gravity?
Isaac Newton
What two factors may slow the vehicle down?
Forces such as friction (between wheels and track, and in bearings) and air resistance act to slow the vehicle down.
What is conservation of energy?
No form of energy is created on its own, it is always converted from one form to another.
What is X’s law of gravity?
Gravity is universal and affects all objects in the universe.
What is friction?
A force that opposes the relative motion between two surfaces in contact, acting in a direction opposite to the movement or attempted movement
What are the two factors that contribute to kinetic energy of a moving object?
mass and velocity.
What two factors affect the force of gravity between objects?
Distance apart and mass
What is momentum?
Product of an object’s mass and velocity
What three factors contribute to the potential energy of a stationary object at a certain height?
Mass, height, and acceleration due to gravity.
Jack throws a cantaloupe in the air and Jill throws an egg. Jill is twice as strong as Jack. Whose object will go higher? Whose object will come to the ground faster?
