Acceleration

Front

What is acceleration?

Back

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

Front

What does it mean if an object is at rest?

Back

An object is at rest if it is not changing its position over time.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time without changing its speed.

Front

What is the difference between acceleration and deceleration?

Back

Acceleration refers to an increase in speed, while deceleration refers to a decrease in speed.

Front

What does a position vs. time graph show?

Back

A position vs. time graph shows how the position of an object changes over time.

Front

What does a flat line on a position vs. time graph indicate?

Back

A flat line indicates that the object is at rest.

Front

What does a steep slope on a position vs. time graph indicate?

Back

A steep slope indicates that the object is moving quickly.

Front

What is the formula for acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

What is a scenario where a car has no acceleration?

Back

A car with the cruise control set at a constant speed has no acceleration.

Front

What does it mean if an object is accelerating?

Back

An object is accelerating if it is changing its velocity, which can mean speeding up, slowing down, or changing direction.
