Speed and Acceleration Problems

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, indicating how quickly an object is speeding up or slowing down.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is a unit of distance?

Back

Common units of distance include meters (m), kilometers (km), feet, and miles.

Front

What does it mean if an object is stationary?

Back

An object is stationary if it is not moving and its position does not change over time.

Front

How do you calculate distance traveled if you know speed and time?

Back

Distance = Speed x Time.

Front

What is a possible unit for acceleration?

Back

Common units for acceleration include meters per second squared (m/s²).

Front

If a car travels at a steady speed of 60 km/h for 2 hours, how far does it travel?

Back

Distance = Speed x Time = 60 km/h x 2 h = 120 km.

Front

What does it mean if an object is accelerating?

Back

An object is accelerating if it is changing its velocity, which can mean speeding up, slowing down, or changing direction.
