Speed, Velocity, and Acceleration

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It includes both the magnitude (how fast) and the direction of motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is an example of constant speed?

Back

A car traveling at 60 km/h on a straight road without changing speed.

Front

What is an example of changing velocity?

Back

A car that speeds up from 20 m/s to 40 m/s while turning a corner.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a rock at the top of a hill.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating acceleration?

Back

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