Motion
100: What is motion?
Answer: Motion is a change in an object’s position over time.
100: What is speed?
Answer: Speed is a measure of the distance an object moves in a given amount of time.
100: What is acceleration?
Answer: Acceleration is the rate at which velocity changes.
100: What does Newton's First Law state?
Answer: An object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force.
200: What describes an object's location?
Answer: Position describes an object's location.
200: If a car travels 60 km in 5 hour, what is its speed?
Answer : 12 km/h
200: What units are used to measure acceleration?
Answer: Meters per second squared (m/s²).
200: How does mass relate to inertia?
Answer: Objects with more mass have more inertia.
300: If you dive into a pool, what type of energy is primarily involved during the dive?
Answer: Kinetic energy.
300: What is the difference between speed and velocity?
Answer: Velocity includes direction, while speed does not.
300: What happens to the speed of a falling object as it descends?
Answer: It accelerates and its speed increases.
300: What is the equation for Newton's Second Law?
Answer: F=ma (Force equals mass times acceleration).
400: What happens to an object's energy as it moves?
Answer: An object’s energy can be transformed or transferred as it moves.
400: What is a reference point used for speed / velocity?
Answer: It allows you to determine if and how an object is moving compared to something that is stationary.
400: If an object's velocity decreases, what type of acceleration is occurring?
Answer: Negative acceleration.
400: How does friction affect motion according to Newton's laws?
Answer: Friction opposes motion and can slow down moving objects.
500: How does the position of an object relate to its energy?
Answer: An object's position may determine whether it has potential energy.
500: When does an object's velocity change?
Answer: When either its speed or direction changes. (positive same direction, negative opposite direction)
500: How can acceleration be calculated with time?
Answer: Using the formula (Vf - Vi) / T
500: Explain Newton's Third Law of Motion.
Answer: For every action, there is an equal and opposite reaction.
