Front

What is stored energy?

Back

Potential energy is stored energy.

Front

What do we call limitations like 'time, cost and/or materials' within a challenge?

Back

Constraints are limitations like 'time, cost and/or materials'.

Front

When I look for and collect data for mistakes in my design, which step am I at?

Back

I am at the Evaluate solution step.

Front

Which step of the design process includes 'Brainstorming'?

Back

The Generate ideas step includes 'Brainstorming'.

Front

If Maddy walked from home to school, then from the school to the park, and then home, what is her total distance?

Back

Her total distance is 10 km.

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the formula for calculating potential energy?

Back

Potential energy = mass x gravity x height (PE = mgh).

Front

What is the difference between distance and displacement?

Back

Distance is the total path traveled, while displacement is the shortest path from start to finish.

Front

What is a prototype?

Back

A prototype is a working model of a design used to test and evaluate ideas.

Front

What does it mean to evaluate a solution?

Back

To evaluate a solution means to assess its effectiveness and identify any improvements.
