Speed Velocity Acceleration

Front

What is the definition of speed?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is a constant speed?

Back

Constant speed means an object is moving at the same speed over time, without speeding up or slowing down.

Front

What is an example of an object accelerating?

Back

A car speeding up from a stoplight is an example of an object accelerating.

Front

What units are commonly used to measure speed?

Back

Speed is commonly measured in meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces and their directions.

Front

How does net force relate to acceleration?

Back

According to Newton's second law, acceleration is directly proportional to net force and inversely proportional to mass (F = ma).
