Distance Displacement Speed Velocity Acceleration

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like km/h or m/s.

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is a reference point?

Back

A reference point is a starting point used to describe the location or position of an object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can involve changes in speed, direction, or both.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the ending point.

Front

If a car travels 100 km in 2 hours, what is its speed?

Back

Speed = Distance / Time = 100 km / 2 h = 50 km/h.

Front

If a runner completes a 400 m lap, what is the distance covered if they run 4 laps?

Back

Distance = 4 laps x 400 m/lap = 1600 m.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a cyclist travels 30 km North and then 40 km East, what is the displacement?

Back

Displacement can be calculated using the Pythagorean theorem: √(30² + 40²) = 50 km.

Front

What is the unit of measurement for velocity?

Back

The unit of measurement for velocity is typically meters per second (m/s) or kilometers per hour (km/h).
