RP 2-2 Acceleration and Graphs

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can involve speeding up, slowing down, or changing direction.

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 unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a car accelerates from 0 to 70 m/s in 10 seconds, what is its acceleration?

Back

7 m/s².

Front

What does a distance vs. time graph show?

Back

A distance vs. time graph shows how the distance traveled by an object changes over time.

Front

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

Back

A flat line indicates that the object is not moving.

Front

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

Back

A steep slope indicates that the object is moving quickly.

Front

What does negative acceleration mean?

Back

Negative acceleration means that the object is slowing down.

Front

What are the three ways an object can accelerate?

Back

An object can accelerate by speeding up, slowing down, or changing direction.

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time.
