## Does acceleration affect the weight of an object?

Yes, apparent weight can change when an object accelerates (e.g., feeling heavier or lighter in an elevator).

## How can acceleration be measured?

Acceleration can be measured using an accelerometer or by calculating the change in velocity over time using speed-measuring devices.

## How does gravity affect acceleration?

Gravity is a type of acceleration, specifically 9.8 m/sÂ² downward near Earth's surface, affecting all objects in free fall.

## What is uniform acceleration?

Uniform acceleration occurs when an objectâ€™s velocity changes by the same amount in equal intervals of time.

## What is negative acceleration?

Negative acceleration (or deceleration) occurs when an object slows down, meaning its velocity decreases over time.

## Can an object have acceleration if its speed is constant?

Yes, an object can have acceleration even if its speed is constant, as in the case of centripetal acceleration, where only the direction of velocity changes (e.g., circular motion).

## What is the difference between speed and acceleration?

Speed is the rate of change of distance, while acceleration is the rate of change of velocity.

## What is Pascal’s Law?

Pascal's Law states that pressure applied to a confined fluid is transmitted equally in all directions. This principle is used in hydraulic systems like car lifts and braking systems.

## Why do we use sharp knives instead of blunt ones?

A sharp knife has a smaller surface area in contact with the object, which increases the pressure for a given force, making it easier to cut.
