What is displacement in motion?
What is displacement in motion?
A vector showing distance and direction from start point.
How is velocity defined?
How is velocity defined?
Rate of change of displacement over time, with direction.
What are the SI units for displacement?
What are the SI units for displacement?
Metres (m) are the SI units for displacement.
How does displacement differ from distance?
How does displacement differ from distance?
Displacement is directional; distance is total path length.
What is the formula for average velocity?
What is the formula for average velocity?
Average Velocity = ΔDisplacement / ΔTime.
How do you convert 90 km/h to m/s?
How do you convert 90 km/h to m/s?
90 km/h = 25 m/s after conversion.
What does the slope of a displacement-time graph show?
What does the slope of a displacement-time graph show?
The slope indicates the velocity of the object.
What does the area under a velocity-time graph represent?
What does the area under a velocity-time graph represent?
The area shows the displacement during that time.
What is a key strategy for solving motion problems?
What is a key strategy for solving motion problems?
Break problems into steps and use diagrams.
What is the difference between velocity and speed?
What is the difference between velocity and speed?
Velocity includes direction; speed is only magnitude.
