Speed and Velocity
What is the average speed if Braden travels 20 meters in 4 seconds?
5m/s
What is the difference between distance and displacement?
Distance is the total path traveled, while displacement is the shortest distance from the start to the end point.
What is Newton's First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
Analyze the graph: What does a flat line indicate?
The object is at rest.
How do engineers calculate average speed for roller coasters?
By dividing the distance by the time taken to complete the segment.
Calculate the speed of a turtle that covers 25 meters in 16.8 seconds.
1.49 m/s
What is an example of a situation where distance is greater than displacement?
Walking in a circle and returning to the starting point.
Explain how unbalanced forces affect motion.
Unbalanced forces cause an object to accelerate or change direction
Which segment of the graph shows the highest speed?
The segment with the steepest slope.
Describe how speed and velocity apply to a roller coaster.
Speed indicates how fast the coaster moves, while velocity includes direction.
What is the speed of a car that travels 30 km in 25 minutes?
1.2 km/min
If a person walks 100 meters north and then returns, what is their displacement?
How does a seatbelt demonstrate Newton's First Law?
It keeps passengers in place during sudden stops, preventing them from continuing forward due to inertia.
Given a distance-time graph, how can you determine the average speed?
By calculating the slope of the line.
How does the design of a roller coaster account for forces?
Engineers consider gravitational force, acceleration, and inertia in the design.
A car drives at a constant speed. What factors could change its speed?
Acceleration, friction, road conditions, and incline
Describe how to interpret a distance-time graph.
The slope indicates speed; a steep slope means high speed, while a flat slope means no movement.
What happens to an object in motion if forces are balanced?
The object maintains its state of motion, either at rest or moving at a constant speed.
Create a distance-time graph using provided data.
Plot the provided distance and time data points on a graph.
How is speed calculated for a journey with stops?
Total distance divided by total time, including stops.
If a motorcycle travels at 25 m/s for 60 seconds, how far does it go?
1500m
In terms of graphs, what does a steep slope indicate?
It indicates a high speed.
Provide an example of unbalanced forces in everyday life.
A car accelerating when the driver presses the gas pedal.
Interpret the motion of a turtle from a distance-time graph.
Analyze the slope and changes in the line to determine speed and stops.
How does understanding speed and velocity impact engineering decisions?
It ensures safety and performance in design and construction.
