Physics

For an object in the gravitational field of the Earth, the mechanical system is the object and the Earth. The force [interaction] is described by…

Example: A steelball with mass in = 0.44 kg and radius r = 1.0 cm moves along a rollercoaster. Seven photogates are placed along the…

Example: An object with mass m = 3.2 kg sits on an incline plane at an angle θ = 23°. The object slides down the…

We start from the kinematics equation in one dimension with time eliminated, v2 – v02 = 2aΔx. We multiply by the mass of the object…

Example 1: An object goes around a vertical circular track, as shown. Find the minimum speed of the object near the top of the loop,…

In uniform circular motion, the object travels with constant speed v along a fixed circular trajectory with radius r. The speed and radius determine the…

The weight W = mg is the gravitational force that the Earth exerts on an object with mass (m). In general, there is an attractive…

Example 1: A projectile is launched with V0 = 19.2 m/s at angle θ0 = 38.7°. a) Does the projectile `clear’ a 3.0 m- high…

Example 1: Emmy starts at time t = 0 and drives along a straight path: she starts at point A, drives straight to point B,…

Physical quantities are measured using instruments; a meter stick for length (L), a clock for time (T), and a balance scale for mass (m). Thus,…
