Motion and Forces

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, regardless of direction.

Front

What is the definition of velocity?

Back

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

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 instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration.

Front

What factors affect the acceleration of an object?

Back

Mass of the object and the net force acting on it.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).
