CFA: Force and motion (Chap. 3)

Explore Force and Motion! Practice vocabulary, energy, and physics concepts with this interactive worksheet.

Matching Match the vocabulary word with the correct definition. cause an event that leads to a result or change effect the result or change that happens because of an event exert to apply a force friction a force between an object and the surface it is moving on infer to reach a conclusion using evidence and reasoning mass the amount of matter that makes up an object matter anything that has mass and takes up space velocity speed in a particular direction Energy Sort the objects by which type of energy they contain (3 in each). Kinetic baseball hit off of a bat spinning fan leaves blowing on the ground Potential car at the top of a hill battery an apple No Energy an unlit candle a pillow a penny on the ground Cause and Effect Choose the correct {potential} cause for each provided effect. Cause Effect thrusters exerted correct force on a normal massed pod the pod docked correctly at the station thrusters exerted correct force on a more massive pod the pod slowed, but then collided with the station the less massive podcollided with a more massive Space Station the pod began to move in the opposite direction thrusters exertedmore than normal force on a normal massed pod the pod made no contact with space station and began moving opposite direction Fill in the blanks with the correct key term (spell correctly).Word Bank:mass velocity force opposite same stronger Key Concepts:A force causes a change in an object's velocity. A stronger force causes a greater change in velocity. With a given force, the object's mass determines the velocity change. A less massive object will experience a greater change in velocity compared to a more massive object (when the same force is exerted). When two objects collide, the both experience the same strength force, but in opposite directions. What happened in the "missing seconds"? the thrusters worked correctly, but the pod was less massive than normal, causing it to be change direction the thrusters worked correctly, but the pod was more massive than normal, causing it to be slowed not stopped and then it collided with the space station the thrusters exerted a force greater than normal, causing the pod to move in the opposite direction
