Question
A car has a resultant force of 2000 N acting on it and accelerates at a rate of 5 m/s². Calculate the mass of the car Explain your answer using Newton's laws of motion and resultant force.
Answer
400 kg
Explanation
A strong answer should address calculate mass from resultant force and acceleration directly. Use the context of Newton's laws of motion within Forces and motion, then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps mass and weight distinct, and links the conclusion back to the approved learning objective.
Common mistake
Common Mistake in Calculating Mass
Students often confuse the formula for calculating mass from resultant force and acceleration, sometimes using the wrong equation or misinterpreting the variables.
To calculate mass, use the formula: mass = resultant force / acceleration. Ensure you correctly identify resultant force in newtons and acceleration in m/s².
