Unit CF object exerts on the first? Did any factors, such as relative mass or relative speed, seem to make a difference to the results? $2. A man pushes a crate across the floor by applying a 135 N force to it. As a result, the crate gradually increases in speed as it moves. Is the strength of the force that the crate applies to the man less than, equal to, or greater than 135 N? Explain how you know. S3. Now reconsider the situation from the Initial Ideas section of this activity, in which pick-up truck and box van collide. The box van has the greater mass, but the pick-up has a higher speed. How would the forces they exert on each other during the collision compare? a) To show your thinking, use the pictures below to draw separate force diagrams for each vehicle during the collision. Briefly explain your diagrams. b) Why does the collision have a greater effect on the pick-up truck than it does on the box van? (Hint: Consider what you have learned about what determines the effect a force has on an object of a particular mass.)isors. This will be done both while the carts are increasing speed and also while they are moving at a constant speed. In both cases, how did the relative force strengths compare? Were they very different or about the same? Summarizing Questionssur toniminutes S1. For each of the situations you explored in this activity, how did the strength and direction of the force that one object exerts on the other during an interaction compare with that of the force that the second CF-31 CF-33
