What is push?
Some students apply force to a toy car on a ramp to push it down. The students measure how fast the car rolls down the ramp. If students want to increase the speed of the car down the same ramp, what should they do?
What is increase the force applied to the car, or adjust the angle of the ramp higher?
What is a type of friction which slows objects moving through air?
What is air resistance?
A ball with more mass collides into a ball with lesser mass at the same speed. Both balls will transfer their kinetic energy into each other. What is likely to happen?
What is the the ball with the greater mass to cause the baller with lesser mass to bounce off in another direction?
The type of force which results in movement?
What is an unbalanced force? One force is stronger that another.

What is the dresser moves towards Rodrigo?
While on a camping trip, Nadely and Abigail are traveling in a boat on a river. On their trip, the river's current carries them down the river at a speed of 5 meters per second (m/s). They don't need to row because the current is carrying them in the direction they need to go. If no other forces are acting on the boat, describe the motion of the boat as it travels downstream?
