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

Define constant speed.

Back

Constant speed means an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

Front

What does a graph showing a straight horizontal line indicate?

Back

A straight horizontal line on a distance-time graph indicates that the object is not moving.

Front

What is deceleration?

Back

Deceleration is a decrease in speed or a negative acceleration.

Front

What does a steep slope on a distance-time graph represent?

Back

A steep slope indicates a high speed; the steeper the slope, the faster the object is moving.

Front

What is the significance of the area under a speed-time graph?

Back

The area under a speed-time graph represents the distance traveled by the object.

Front

What does it mean if an object is returning to its starting position?

Back

It means the object has moved away from its starting point and is now moving back towards it, resulting in a net displacement of zero.

Front

How can you identify acceleration on a graph?

Back

Acceleration can be identified by the change in the slope of a speed-time graph; a curve indicates changing speed.

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

Back

A negative slope indicates that the object is moving back towards the starting point.
