Calculating Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity, meaning it has both magnitude and direction.

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

If a car accelerates from 0 to 60 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (60 m/s - 0 m/s) / 5 s = 12 m/s².

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position, along with the direction.

Front

What is uniform acceleration?

Back

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

Front

What is the formula for calculating displacement with constant acceleration?

Back

Displacement (s) can be calculated using the formula: s = ut + (1/2)at², where u is the initial velocity, a is the acceleration, and t is the time.

Front

What does it mean when an object has zero acceleration?

Back

Zero acceleration means that the object's velocity is constant; it is either at rest or moving at a constant speed in a straight line.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration, also known as deceleration, indicates that an object is slowing down.

Front

How does gravity affect acceleration?

Back

Gravity causes objects to accelerate towards the Earth at approximately 9.81 m/s², regardless of their mass.
