A negative instantaneous acceleration means the velocity is decreasing. If it is positive, our velocity is increasing. Using Calculus to Find Acceleration Acceleration is measured as the change in velocity over change in time (ΔV/Δt), where Δ is shorthand for “change in”. For example, le...
called instantaneous velocity. In order to find the instantaneous velocity of the particle previously discussed at pointP_1, we must move pointP_2 closer to pointP_1 and calculate the average velocities between the two points as they become exceedingly closer. As Δ_xand Δ_tbecome smaller, ...
Damien has a master's degree in physics and has taught physics lab to college students.Cite this lesson Angular velocity and linear velocity are the two types of object velocity. Learn how to find the angular velocity of an object and understand how to convert it to linear velocity. Angular...
Edward Farhi, an MIT physicist who researched strangelets, thinks the most likely place to find strange matter is in neutron stars. These collapsing stars compress their interiors forcefully. "At the core, you have densities and pressures large enough to form strange matter. If strange matter for...
Instantaneous velocity describes the magnitude of velocity at any point and uses the same formula as average velocity. The difference is that it uses a near-zero change in time to minimize the effects of averaging. Another component of velocity is acceleration, which increases (or decreases) veloc...
Electrolyte-filled subnanometre pores exhibit exciting physics and play an increasingly important role in science and technology. In supercapacitors, for instance, ultranarrow pores provide excellent capacitive characteristics. However, ions experience d

One key aspect astronomers hoped to measure was the mass of a galaxy. But you can't just weigh something the size of a galaxy – you have to find its mass by other methods. One method is to measure the light intensity, or luminosity. The more luminous a galaxy, the more mass it pos...
If you want to calculate the acceleration, first you need to modify the force equation to get a = F/m. When you plug in the numbers for force (100 N) and mass (50 kilograms), you find that the acceleration is 2 m/s2. HowStuffWorks You may be surprised to learn that Newton wasn...
