What causes a soccer ball to move? In flight, the ball rotates about the center of gravity. Newton’s laws of motion describe the translation of the center of gravity. As the ball moves through the air, the air resists the motion...
What is the speed of a 0.15 kg baseball? Final answer: The speed of a 0.15-kg baseball with 77 J of kinetic energy is approximately 40.82 m/s. This is found using the kinetic energy formula and solving for velocity. Can accelerate...
What forces act on a moving tennis ball? Thrust – momentum of the racquet pushing the ball forward. Gravity – the weight of the ball acts downward from the ball’s center of gravity. Drag – refers to the force, in this...
What is the speed of a tennis ball on the return of a serve? Short Answer. The speed of a tennis ball can be as fast as the serve on the return even if the racket is not swung very fast...
What is the acceleration of a tennis ball as it leaves your hand? Assume that air resistance is negligible, so the tennis ball can be considered to be in free-fall, with an acceleration of magnitude g = 9.80 m/s^2. Which of...
What is moving away from the body midline? Abduction is a movement away from the midline – just as abducting someone is to take them away. For example, abduction of the shoulder raises the arms out to the sides of the...
What is the wavelength associated with a moving particle? The wavelength λ associated with a moving particle depends upon its mass (m) velocity (v) and Planck’s constant ‘h’. Show dimensionally that λ∝hmv. What is a wave associated with every moving particle?...
What is the speed and direction of a moving object? Velocity is a vector which has a magnitude and direction. The magnitude (or value) of the velocity is the object’s speed. The direction of the velocity vector is the direction which...
What is the process of moving and grinding food? Mechanical breakdown is when you physically break food into pieces. Mechanical breakdown starts in the mouth, with the teeth tearing, ripping, and grinding food into smaller pieces. The mechanical breakdown also occurs...
What is the moving of sediments from the original position? Erosion – Erosion is actually many processes which act together to lower the surface of the earth. In terms of producing sediment, erosion begins the transportation process by moving the weathered...
