What are examples for motion?
A ball rolling down a hill.
Describe the motion of a ball in a typical sport?
Since a ball is a sphere the motion it makes is rolling. The rolling happens on the ground and in the air.
What is a force that opposes the motion of a ball rolling across the ground?
The force that opposes the motion of a ball rolling across the ground is called friction. Friction is caused by the contact between the rough surfaces of the ball and the ground, which creates resistance that slows down the ball's motion.
What form of energy did the table tennis ball have when it was rolling?
Rolling (motion) is an example of Kinetic Energy.
What is example of motion?
An example would be a ball rolling down a hill. The ball rolling down would show motion.
A soccer ball rolling across a field has energy of motion?
Is that a ? no it's not!
Does a ball rolling have kinetic energy?
Yes, a rolling ball has kinetic energy due to its motion. The amount of kinetic energy it has depends on its mass and velocity.
What force causes the motion to stop when a soccer ball is rolling across the grass and begins to slow down then stops?
The main force that causes the soccer ball to stop rolling is friction between the ball and the grass surface it is rolling on. As the ball moves, the grass exerts a force in the opposite direction of the ball's motion, gradually slowing it down until it comes to a stop.
Is a ball rolling down a ramp uniform motion?
No, a ball rolling down a ramp is not considered uniform motion because its speed changes as it moves due to the force of gravity. Uniform motion occurs when an object moves in a straight line with a constant speed.
Why does a ball rolling on the ground slow down?
A ball rolling on the ground slows down due to friction between the ball and the surface it is rolling on. As the ball moves, frictional forces act in the opposite direction of its motion, causing it to lose kinetic energy and gradually slow down. Additionally, air resistance may also contribute to the slowing down of the ball.
Forces used in a rolling ball?
The main forces acting on a rolling ball are gravity, which pulls the ball downward, and normal force, which acts perpendicular to the surface the ball is rolling on. Additionally, there is friction force between the ball and the surface, which helps propel the ball forward or slow it down depending on the direction of motion.
What forces act on a rolling ball?
It acts as a rolling friction or rolling resistance when it starts to roll on a flat surface , it resists the direction of rotation of the object in both clock wise and anti clock wise direction.
