Kinematics - Study guides, Class notes & Summaries

When you drive a car and take a quick look on the speedometer, what do you see velocity or speed? Speed. A ball is thrown vertically up and is caught at the starting point; compare the traveled distance and displacement of the ball. Displacement is zero, while distance is 2h Can an object with a constant acceleration reverse it direction of travel? Explain. Yes, an initial velocity in one direction with the acceleration in the opposite direction, causing it to reverse the direct...

kinematics the study of how motion occurs without consideration to why it occurs scalars quantities, such as temperature or distance, that are just numbers without any direction vectors quantities that have both a magnitude and a direction distance total length displacement net length average velocity displacement/change in t average speed distance/duration of time negative slope on position vs time graph object goes backwards posit...

If given a velocity vs time graph, is the displacement determined by the slope or the area of the graph? Area A hippo walks from +2.0 to -1.5 to +4.0 to -3.5 on the number line in 6 seconds. What is the hippo's velocity? -0.917 m/s Convert 35 m/s to km/hr. 126 km/hr If given an acceleration vs time graph, is the velocity determined by the slope or the area of the graph? Area An object can be moving but not accelerating. True The shape of an acceleration-t...

Equation for distance? When does this only work with? d = vt (only works with constant velocity) Equation for acceleration? a = v/t vad equation? vf^2 = vi^2 +2ad Two equations for velocity? v = d/t v = at Absolute value of average velocity = ? |Vave| = change in distance / change in time When velocity is constant, what do you know about acceleration? a = 0 (zero) Magnitude? - how much? how large? - always positive because it is the absolute val...
