What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up), negative (slowing down), or zero (constant speed).

Front

What is the formula for acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object's speed increases over time.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object's speed decreases over time.

Front

What is uniform acceleration?

Back

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

Front

What is non-uniform acceleration?

Back

Non-uniform acceleration occurs when an object's acceleration changes over time.

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 air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, affecting its acceleration.

Front

How does mass affect acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass; heavier objects require more force to accelerate.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no air resistance.
