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

What is the formula for calculating acceleration?

Back

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

Front

What does a positive acceleration indicate about an object's motion?

Back

A positive acceleration indicates that the object is speeding up.

Front

What does the slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents acceleration.

Front

If an object is in free fall, what is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.81 m/s².

Front

How do you calculate the distance fallen by an object in free fall?

Back

The distance (d) fallen can be calculated using the formula: d = 0.5 * g * t², where g is the acceleration due to gravity and t is the time in seconds.

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 significance of a negative acceleration?

Back

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

Front

How can you determine the acceleration of an object from a velocity-time graph?

Back

The acceleration can be determined by calculating the slope of the line on the velocity-time graph.
