Physics Acceleration

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

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 does it mean if an object has zero acceleration?

Back

An object has zero acceleration if it is moving at a constant velocity or is at rest.

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 uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

What is the formula for calculating final velocity?

Back

Final velocity (v) can be calculated using the formula: v = initial velocity + (acceleration × time).

Front

What is the significance of negative acceleration?

Back

Negative acceleration, or 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.
