What else can I help you with?
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.
Examples of when a force causes an object to stop moving?
Take a ball and push it an angle yo direction of motion.what do you observe? Answer-change the angle of your hand with respect to the direction of motion of the ball.Does yoo effort result in change in direction of motion of ball?
Describe contact force and noncontact force that affect the motion of a baseball a pitcher has thrown the ball?
The contact force will keep the ball moving but as the ball goes farther the ball slows down that's were the non contact force comes in it makes the ball not in contact
A ball falls 5 m and then bounces to a height of 3 m What height is the best reference point for the motion of the ball?
5 m
How do you Draw a picture describing how force and motion act on an object?
Show a picture of a football player kicking a ball.
The motion of a 150g ball is more difficult to change than the motion of a 50g ball because the 150g ball has?
more inertia due to its greater mass, making it resist changes in its velocity or direction more than the lighter 50g ball.
What size s a cricket ball?
150g
What happens to the direction of motion of the ball what changes it direction of motion?
The direction of motion of a ball changes when an external force acts on it, such as a kick or a collision with another object. This force causes the ball to accelerate or decelerate in a different direction than its initial path.
How does inertia explain why it would be so difficult o play softball with a bowling ball?
Inertia is the resistance of an object to change its state of motion. A bowling ball has more mass compared to a softball, so it has greater inertia. This means it would be more difficult to accelerate, decelerate, or change its direction when playing softball, making it harder to control compared to a lighter and less massive softball.
What are three contact forces that can change the motion of a ball?
force,motion,and friction
How does the motion of a ball swinging on a string demonstrate the principles of physics?
The motion of a ball swinging on a string demonstrates principles of physics through concepts like centripetal force, acceleration, and conservation of energy. The ball's circular motion is maintained by the tension in the string providing the centripetal force needed to keep it moving in a curved path. The ball's speed and direction change as it swings, showing how acceleration affects motion. Additionally, the ball's potential and kinetic energy change as it moves, illustrating the conservation of energy principle in action.
A rolling bowling ball is hard to stop because?
it has momentum due to its mass and velocity. The rolling motion creates kinetic energy that makes it difficult to slow down or stop abruptly. friction between the ball and the surface also plays a role in resisting its motion.
What type of motion is there in a bouncing ball?
A bouncing ball undergoes a combination of translational and rotational motion. Translational motion refers to the ball moving from one location to another, while rotational motion involves the spinning or rotation of the ball as it bounces. These two types of motion work together to create the overall bouncing motion of the ball.
Which forces always cause a change in motion?
The forces that always cause a change in motion are unbalanced forces. When there is an imbalance of forces acting on an object, it will accelerate or decelerate, causing a change in its motion. Balanced forces, on the other hand, do not cause a change in motion as they cancel each other out.
What causes a change in motion a balanced or unbalanced force?
Forces on a moving object are balanced only when the object is moving at a constant velocity. Remember, acceleration is a force and a constant velocity is equivalent to zero acceleration. Think of a ping pong ball that you drop from a few meters above the ground: After a short acceleration the ball reaches "terminal velocity" when the air resistance balances the gravitational acceleration. After this, the forces on the ball are balanced (although it is moving, the velocity - speed & direction - of the ball is not changing)
Which has more inertia-a cricket ball or a rubber ball?
The cricket ball has more inertia than the rubber ball because inertia is directly proportional to mass. The cricket ball is denser and heavier than the rubber ball, making it harder to change its state of motion.
What is the motion of a ball around a rod?
The motion would be circular characteristic of the centripital forces applied to the ball.
