Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

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 it mean when an object has zero acceleration?

Back

An object has zero acceleration when it is moving at a constant velocity, meaning its speed and direction do not change.

Front

Can an object accelerate while maintaining a constant speed?

Back

Yes, an object can accelerate if its direction changes, such as a car turning a corner at a constant speed.

Front

What is the difference between positive and negative acceleration?

Back

Positive acceleration occurs when an object speeds up, while negative acceleration (deceleration) occurs when an object slows down.

Front

What is uniform acceleration?

Back

Uniform acceleration refers to a constant acceleration, where the rate of change of velocity is the same over time.

Front

What is the significance of a velocity-time graph with a horizontal line?

Back

A horizontal line on a velocity-time graph indicates that the object is moving at a constant velocity, hence zero acceleration.

Front

How does friction affect acceleration?

Back

Friction opposes motion and can reduce the acceleration of an object, depending on the surface and the force applied.

Front

What is the relationship between acceleration and net force?

Back

According to Newton's second law, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass (F = ma).

Front

What is the unit of acceleration in the SI system?

Back

The unit of acceleration in the SI system is meters per second squared (m/s²).
