1. List 3 things that can cause a change in velocity. Change in speed Change in direction Change in both speed and direction

How much faster are they moving at 25 seconds compared to 5 seconds.

What is the independent variable? Dependent variable?

Is the red or blue line going faster at 3- 4 hours into trip?

What is the dependent variable? Independent variable? Type of Surface

If an action force is a golf club hitting a ball, what is the reaction force? The ball hits the golf club

If a desk pushes down with a force of 50N, what direction and magnitude is the force of the floor on the desk? 50N Up

If a rocket is moving at 100meters per second, what will happen to speed if: Forces are balanced? It will keep moving 100m/s It turns on it’s engines? It will change velocity (speed up, slow down, change direction depending on direction of engine force)

If the length of the arrows represent the magnitude, Which direction will this object move? Down and to the right
