Speed, Velocity, and Acceleration

Front

What is the definition of speed?

Back

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

Front

What is the formula for calculating average speed?

Back

Average speed is calculated using the formula: Average Speed = Total Distance / Total Time.

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 per unit of time, typically expressed in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is instantaneous speed?

Back

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

Front

What happens to the speed of an object at its highest point when thrown vertically?

Back

At the highest point, the instantaneous speed of the object is 0 m/s.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, is the rate at which an object slows down.

Front

What is the formula for calculating distance when given speed and time?

Back

Distance can be calculated using the formula: Distance = Speed x Time.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.
