Let\u2019s break down each quantity:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">\u2705 <strong>Speed<\/strong> \u2013 <strong>Constant<\/strong><\/h4>\n\n\n\n<p>Speed is the scalar measure of how fast an object moves, regardless of direction. In uniform circular motion, the object travels equal distances in equal intervals of time around the circle, so <strong>speed remains constant<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">\u274c <strong>Velocity<\/strong> \u2013 <strong>Not Constant<\/strong><\/h4>\n\n\n\n<p>Velocity is a <strong>vector<\/strong> that includes both <strong>magnitude (speed)<\/strong> and <strong>direction<\/strong>. Although the speed is constant, the <strong>direction<\/strong> of motion changes continuously as the object moves around the circle. Therefore, the <strong>velocity vector changes<\/strong> at every instant.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">\u2705 <strong>Angular Velocity<\/strong> \u2013 <strong>Constant<\/strong><\/h4>\n\n\n\n<p>Angular velocity is the rate at which the angle changes with time, measured in radians per second. In uniform circular motion, the object sweeps out equal angles in equal times, so the <strong>angular velocity remains constant<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">\u274c <strong>Centripetal Acceleration<\/strong> \u2013 <strong>Not Constant (in direction)<\/strong><\/h4>\n\n\n\n<p>While the <strong>magnitude<\/strong> of centripetal acceleration (given by ac=v2ra_c = \\frac{v^2}{r}ac\u200b=rv2\u200b) is constant (since speed and radius are constant), the <strong>direction<\/strong> of this acceleration constantly changes\u2014it always points toward the center of the circle. Hence, <strong>centripetal acceleration as a vector is not constant<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">\u2705 <strong>Magnitude of the Net Force<\/strong> \u2013 <strong>Constant<\/strong><\/h4>\n\n\n\n<p>The net force acting on the object is the <strong>centripetal force<\/strong>, which has a constant magnitude of F=mv2rF = \\frac{mv^2}{r}F=rmv2\u200b. Though the <strong>direction<\/strong> changes (always toward the center), its <strong>magnitude remains constant<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator
