Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

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 formula for displacement?

Back

Displacement is calculated as: Displacement = final position - initial position.

Front

What is the difference between distance and displacement?

Back

Distance is the total path traveled, while displacement is the shortest straight-line distance from the initial to the final position.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a fixed speed in a straight line without changing direction.

Front

What is the significance of negative acceleration?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.

Front

How do you interpret a velocity-time graph?

Back

The slope of a velocity-time graph represents acceleration; a flat line indicates constant velocity.

Front

What is the unit of measurement for velocity?

Back

Velocity is measured in meters per second (m/s).

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 direction.
