1st Period Motion Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What does a positive slope on a distance-time graph indicate?

Back

A positive slope indicates that the object is moving away from the starting point at a constant speed.

Front

What does a negative slope on a distance-time graph indicate?

Back

A negative slope indicates that the object is returning to the starting point.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / 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 a stationary object?

Back

A stationary object is one that is not moving; its position does not change over time.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time, where displacement is the change in position.

Front

What does it mean if an object is accelerating?

Back

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

Front

What are the two measurements necessary for calculating speed?

Back

Distance and time.

Front

What does a flat line on a distance-time graph represent?

Back

A flat line represents a stationary object, meaning it is not changing its position over time.
