Choose the correct answer: A student pushes a cart with 15 N of force. Another student pushes in the opposite direction with 15 N. What will happen?

Choose the correct answer: A 4-kg object accelerates at 3 m/s². What is the net force acting on the object?

Choose the correct answer: Which situation shows balanced forces?

Choose the correct answer: A magnet pulling a paperclip involves what type of force?

A student pushes a 2-kg box with 10 N of force. The box accelerates at 4 m/s^2. How much friction is acting?

A team created a prototype bridge, but it collapsed when tested. Which design step should they return to?

Students are asked to build a structure that can hold 20 textbooks. What is this describing?

A team has only 20 minutes and limited materials. What part of the design process are these details?

Students draw different possible bridge shapes before choosing one. What step is this?

After testing their bridge, students write a report explaining what happened and what they would fix. Which step is this?

A group discovers their bridge holds weight but sways too much. What should they do first?

Students want to reduce bending in the center of their model bridge. Which improvement is MOST effective?

Which scenario shows the testing stage?

A team must finish their design using only 50 sticks and 30 minutes. What is this?

A team builds 3 prototypes and tests each one. Why is this a good engineering strategy?

A student drops a weight onto their bridge model to test strength. What force is acting downward?

A bridge needs to support a moving load (like cars). Which force will vary the most?

After testing, students find cracks in the joints of their bridge. What is the MOST reasonable next step?

A team records data showing how much weight their bridge held before breaking. What part of the process is this?
