10 Questions
What is the direction of acceleration for an object on a ramp?
Toward the direction that reduces the object's potential energy as rapidly as possible.
How does the force and distance relate to work on a ramp?
Work is equal to the force multiplied by the distance, where force and distance are in the same direction.
What is the difference in work done on a shallow ramp versus a steep ramp?
The force and distance are different on a shallow ramp versus a steep ramp, but the work done is the same.
What is the formula for kinetic energy?
Kinetic energy is equal to ½ Mass x Speed.
What are the different forms of potential energy?
Gravitational, magnetic, electrochemical, nuclear, elastic, electric, and chemical.
What is thermal energy?
Thermal energy is the same forms of energy, but divided up into countless tiny fragments.
What is the net force on a metro train traveling at constant velocity?
The net force is zero on all cars of the train.
What determines the direction of acceleration on a ramp?
The direction that reduces the object's potential energy as rapidly as possible.
What is the formula for work?
Work = Force x Distance, where force and distance are in the same direction.
What is the relationship between force and distance on a ramp?
The force and distance are inversely proportional to each other.
Understand the concept of inertia and its application in real-life scenarios, including skating. Explore how objects in motion tend to remain in motion, and objects at rest tend to remain at rest, with demonstrations of razor scooters and air hockey pucks.
