Which law is summed up by the following equation: f=ma? What two things does gravitational force depend on? What is the path of a projectile? When will the following hit the ground: feather and bowling ball? And what about if there was an absence of air? What is acceleration due to gravity? (It is a number) If you press 50 N on the wall and it doesn’t move, what force is the wall pressing back? Rocket Propulsion is an example of what? Friction between a tire of a moving truck and the highway is what type of friction? How many basic forces are there? What are the four basic forces? 4 point question A roller coaster going around a sharp curve is subject to what type of force? What is the largest velocity felt by a falling object? When a car moves in a circle, what kind of acceleration does it have? What is the property of a moving object resulting from its mass and velocity? What is this an equation of: mass x gravity? What is weight measured in? What is a term that tells you the amount of force needed to move an object? Is momentum lost, destroyed, or transferred? If you have a paper bag that is flat and one that is crumbled, which one will hit the ground first? When you are trying to push a box across the floor and it doesn’t move, what kind of force is acting upon it? What kind of force do you have when the box starts sliding? What are the points you measure distance from known as? What are the areas known as that stick together and are a source of friction? The law of ______ provided scientists with a way to find new, distant planests. Which law states that for every force there is an equal and opposite reaction? What tells you that momentum can be transferred between objects? What is the distance an object travels per unit of time? What is a change of velocity’s rate? A Push or a Pull is known as?
