Energy, Forces and Motion 2

Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in miles per hour (mph) or meters per second (m/s).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is a constant speed?

Back

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

Front

What is a distance-time graph?

Back

A distance-time graph shows how the distance of an object changes over time, with distance on the vertical axis and time on the horizontal axis.

Front

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

Back

A steeper slope indicates that the object is moving faster.

Front

What is the importance of precise measurements in experiments?

Back

Precise measurements ensure that experiments can be replicated and that results are reliable.

Front

What is a hypothesis in scientific experiments?

Back

A hypothesis is a testable prediction about the relationship between variables in an experiment.

Front

What is the role of a control in an experiment?

Back

A control is a standard for comparison that helps to isolate the effects of the independent variable.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the endpoint.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.
