Why is riding a bike rolling friction?
Riding a bike experiences rolling friction because the tires are in contact with the ground and the force needed to overcome the resistance of the surface and keep the wheels rolling creates this friction. The deformation of the tire as it grips the ground and the energy loss due to internal friction within the tire also contribute to rolling friction.
For each of the following situations state if the object has potential energy or kinetic energy. (a) a bowling ball rolling down the aney (b) a book sitting on the top sheIf of a bookcase?
(a) The bowling ball rolling down the alley has kinetic energy due to its motion. (b) The book sitting on the top shelf of the bookcase has potential energy due to its position above the ground.
Will a car or a bowling ball hit the ground first?
Both the car and the bowling ball will hit the ground at the same time, assuming they are dropped from the same height in a vacuum. This is because all objects fall at the same rate of acceleration due to gravity, regardless of their mass.
Does a marble and a bowling ball hit the ground at the same time?
In a vacuum, they would hit the ground at the same time due to gravity. However, in the real world with air resistance, the bowling ball would typically hit the ground first because it has more mass and air resistance affects lighter objects more.
Why does an ice-hockey puck have less friction than a ball rolling on the ground?
An ice hockey puck has less friction than a ball rolling on the ground because the puck's smooth, flat surface makes contact with the ice, reducing friction. In contrast, a ball rolling on the ground has more points of contact with the rough surface, leading to increased friction that slows it down. Additionally, the presence of air between the ball and the ground can also contribute to more friction.
Will a bowling ball or golf ball hit the ground first?
The bowling ball will hit the ground first because it has more mass than the golf ball, so it experiences a greater force of gravity pulling it downward. This causes the bowling ball to accelerate more quickly than the golf ball, making it reach the ground sooner.

Is a bowling lane level?
No. It is on even ground.
What will hit the ground first a bowling ball or an apple?
Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.
Imagine an experiment in which a 16lb bowling ball and a 10lb bowling ball are dropped from the fifth floor at the same time The heavier ball will reach the ground first?
No. They will hit the ground at the same time. The inertia for the heavier ball will be greater, but the acceleration for both will be the same, and both would (if the air resistance is the same for both) hit at the same time.
What would happen if there was no friction when a tire was rolling on the ground?
It would keep rolling.

no
What can move the ground with a rolling up-and-down motion?
An earthquake.
