• #### Drag Forces | Physics Lumen Learning

Particles in liquids achieve terminal velocity quickly. One can measure the time it takes for a particle to fall a certain distance and then use Stokes' law to calculate the viscosity of the liquid. Suppose a steel ball bearing (density × 10 3 kg/m 3, diameter mm) is dropped in a container of motor oil. It takes 12 s to fall a distance of m.

• #### Collisions and Momentum PHYSICS

down a ramp, a steel ball leaves the ramp with a horizontal velocity v. At any point in the trajectory of this ball, the horizontal component of this velocity will remain constant if air friction is negligible. The vertical ycomponent of the velocity will increase according to the acceleration due to gravity (g); its initial value is zero. The ball strikes the floor after

• #### 1D Kinematics: Describing the Motion of Objects

Kinematics is the science of describing the motion of objects. Such descriptions can rely upon words, diagrams, graphics, numerical data, and mathematical equations. This chapter of The Physics Classroom Tutorial explores each of these representations of motion using informative graphics, a systematic approach, and an easytounderstand language.

PHYSICS MIDTERM REVIEW 12. Base your answer to the following question on the information and diagram below. An inclined plane is 10 meters long and is elevated 5 meters on one end as shown. Starting from rest at the top of the incline, a box weighing 100 Newtons accelerates down the incline at a rate of meters per second 2.

• #### The Physics of Tennis | Basic Tennis Physics

Gravity: An equation for the magnitude of the force of gravity on the ball is given by: where m is the mass of the ball, approximately 57 g by regulation ( Source: ), and g is the acceleration due to gravity near the surface of the earth, . Thus there is a constant downward force of on the ball at all times.

• Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward.

• #### Q A: Height of ball bounce | Department of Physics ...

Oct 22, 2007· A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy. After the bounce, the ball and the ground or floor have absorbed some of that energy and have become warmer and have made a noise.

• #### Force of a Golf Club on a Golf Ball The Physics Factbook

The golf club only comes into contact with the ball for approximately 1/200 of a second. The face of the club is grooved so that during contact with the ball it can grip the ball and create backspin which enables aerodynamic lift. While searching for a measurement of the force of a golf club on a golf ball I found four different measurements.

• #### Mastering Physics Solutions: Fun with a Spring Gun

Dec 24, 2011· A springloaded toy gun is used to shoot a ball of mass m = straight up in the air, as shown in the figure. The spring has spring constant k = 667N/m. If the spring is compressed a distance of centimeters from its equilibrium position y=0 and then released, the ball reaches a maximum height h max (measured from the equilibrium position of the spring).
