Speed, Velocity, Acceleration

Front

What is speed?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is velocity?

Back

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

Front

How does acceleration relate to speed and direction?

Back

Acceleration is the rate of change of velocity, which can occur by changing speed, direction, or both.

Front

What is the formula for calculating acceleration?

Back

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

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 does it mean if forces are balanced?

Back

If the sum of the forces acting on an object is zero, the forces are balanced, and the object will not accelerate.

Front

What does it mean if forces are unbalanced?

Back

Unbalanced forces result in a net force acting on an object, causing it to accelerate in the direction of the net force.

Front

How do you calculate the time taken to travel a certain distance at a given speed?

Back

Time = Distance / Speed.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).
