But in 1998, the Hubble Space Telescope observations of distant supernovae showed that the universe was the universe's expansion has increased over time. Though scientists hadn't figured out what exactly was causing the acceleration, this expansion acceleration lead scientists to theorize that dark ...
Which type of force are tension and compression? How to calculate frequency of a pendulum How much tension must a rope withstand if it is used to accelerate a 1,810-kg car horizontally along a frictionless surface at 1.10 m/s2? How does mass and acceleration affect force? How to calculate...
Accelerometers are the stuff of rocket science—quite literally! Mounted in spacecraft, they're a handy way to measure not just changes in rocket speed but also apogee (when a craft is at its maximum distance from Earth or another mass, so its acceleration due to gravity is at a minimum)...
How does surface area affect the acceleration of an object? How are mass and velocity related in circular motion? Why does centripetal force decrease when mass is increased? How are velocity and momentum related? How can a small force impart the same momentum to an object as a large force?
How are weight and gravitational force related? Is force measured in newtons? How to calculate force from momentum? Forces of 3.0 N and 1.0 N act on a 6.0 kg mass as shown below. What is the acceleration of the 6.0 kg mass? What is the difference between magnitude of a force...
It’s also important to mention that since this is an acceleration and not a force, the vehicle’s mass or size doesn’t matter at all. In the harsh driving rules, we specify the vehicle size (passenger car, lorry/cube van, and heavy-duty lorry) as a suggestion. A sports car can ...
How much kinetic energy does this particle gain during the period of acceleration? Give your answer in mJ (1 milli When a ball is hit, it travels at 24.14 meters per second. If the mass of the ball is 0.10 kilograms, what is its kinetic energy (in joules)? Round your final answer ...
Speed and acceleration are two fundamental concepts in mechanics, or the physics of motion, and they are related. If you measure the speed of an object while you record the time, then measure it again a little later, also while recording the time, you can find acceleration, which is the ...
Since the charge is proportional to the force, and the mass is constant, then the charge is also proportional to the acceleration. These sensors are used in a variety of ways – from space stations to handheld devices – and there’s a good chance you already own a device with an ...
2. How is the angular acceleration ? related to the linear acceleration? A. ? = Acceleration / Radius of large disk B.? = Force / mass C.? = Acceleration / Radius of Smart Pulley D.? = m(g-a)R 3. According to the relationship between ...
