Which of the following is an example of an unbalanced force and explain how you know. 1. a tug of war game in which no one wins. 2. a roller coaster going down the first drop. 3. a car parked in a garage. 4. a bridge
What is a roller coaster going down the first drop. I know this because gravity will be the unbalanced force that pulls the coaster car down.

An astronaut weighs 900 N on Earth but 0.0 N in outer space. How can an astronaut weigh different amounts when in different places? Explain mass and weight
What is The astronaut's mass will stay the same in all those places, but his weight changes due to the gravitational pull on him mass. Each place has a different amount of gravitational pull.

A speedboat is moving at a constant speed, and the force propelling it forward is balanced by the force of the water pulling it backward. Suddenly a wave strikes it from the side with a force of 500 newtons What will happen to the motion of the boat when it is hit by the wave?
What is the boat will become unbalanced and tip the opposite of the direction of the force

As an airplane flies through the air there are 4 forces at work. Thrust is caused by the airplane's propellers pushing through the surrounding air, pulling the airplane forward. Drag is caused by the air smacking into the plane's surface, pushing it backward. Lift is caused by the air rushing over the wings, pushing it upward. And weight is caused by gravity. Which force acts from a distance?
What is gravity

Ozzy is trying to tow a trailer up a steep hill. If his truck pulls forward with a force of 2,750 newtons and the weight of the trailer pulls backward with a force of 2,790 newtons, what will be the net force and the direction?
What is the net force will be 40 newtons backwards because it is unbalanced.
