What is acceleration due to gravity on Earth?
What is 9.8 m/s/s?
The type of speed an object travels while in circular motion along the outside of the path.
What is tangential velocity?
A 1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. What is the magnitude of the friction force required to keep the car from sliding?

You are making a circular turn in your car on a horizontal road when you hit a big patch of ice, causing the force of friction between the tires and the road to become zero. While the car is on the ice, it travels ___.

Riding in the bed of a pick-up truck can be very dangerous. If the truck turns suddenly, the riders can be thrown from the truck bed. Why are the riders ejected from the bed?
What is the riders' inertia tends to keep them moving in the same straight-line motion while the truck turns beneath them. The walls of the bed of the pick-up truck are low so won't provide much centripetal force to hold the riders in the truck as it turns.
