Acceleration, Velocity, Speed, Displacement

Front

What is acceleration?

Back

Acceleration is defined as the change in velocity of an object divided by the time interval over which the change occurs.

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the unit of acceleration?

Back

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

Front

What is velocity?

Back

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

Front

How does velocity differ from speed?

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 displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the formula for calculating displacement?

Back

Displacement (s) can be calculated using the formula: s = final position - initial position.

Front

What is the relationship between speed, distance, and time?

Back

Speed is calculated as distance divided by time: Speed = Distance / Time.

If a roller coaster accelerates from 6.0 m/s to 70 m/s in 4 seconds, what is the acceleration?

Back

The acceleration is 16 m/s².

Front

A box slides down an incline and reaches a velocity of 27 m/s in 3 seconds from rest. What is the acceleration?

Back

The acceleration is 9 m/s².
