Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like meters per second (m/s) or kilometers per hour (km/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. 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 that only measures how fast an object is moving, while velocity is a vector quantity that includes both speed 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 30 km/h to 60 km/h while turning a corner.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does it mean if an object has a negative acceleration?

Back

Negative acceleration indicates that the object is slowing down.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.
