In summary, the conversation discusses a problem involving a steel ball bouncing off a wall with a given speed and angle. The question is to find the magnitude of the average force exerted on the ball by the wall in units of N. The attempt at a solution involves finding th...
What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 9.0 m / s when going down a slope for 2.1 s? What is the magnitude of the average acceleration of a skier who,...
speed is the magnitude of the velocity. that's it. as an equation, that would be: this would also make speed a scalar value. an example here is a classic example showing the difference between average velocity and the two definitions of speed. suppose you have a circular race track that...
What is theoretical astrophysics? What is the gravity on Ceres? What is the sun's mass? What is the middle of a black hole called? How close can you get to a black hole? What is the magnitude of the gravitational force acting on the Sun due to the Earth?

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). Speed Each of the possible gear ratios of a bicycle. Acceleration The act of accelerating. Speed The light-gather...
What is SI unit of velocity? Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per seco...
To find the average velocity of the molecules of an ideal gas, we can follow these steps:Step 1: Understand the Concept of Average Velocity Average velocity is defined as the total displacement divided by the total time taken.
Speed and velocity are distinct concepts; while speed only considers the magnitude of movement, velocity also takes into account the direction. The formula for velocity is given by velocity (v)=displacement (d)time (t)velocity (v)=time (t)displacement (d), where displacement is the distan...
