One situation could be when someone is sitting in a car that is travelling at a constant speed of 150mph
Explanation:
Let’s review the terms:
Velocity: the speed of something in a given direction
Acceleration: increase in the rate or speed of something
The car is travelling at a high speed but the speed is constant, so it isn’t increasing. In other words, the car the person is sitting in is travelling in in a high velocity but with no/low acceleration.
I hope this helps! Please comment if you have any questions.

b. Some examples are friction from electricity going through a wire or friction from rubbing your hand together.
c. Without friction, we would fall every time we walked. Because there is friction, we can walk normally. Another example is a ball moving across the field. Without friction, the ball would not slow down.
Explanation:
Overall, friction is important to us because we depend on it.
