Velocity is a vector quantity that has the same direction as the displacement. Displacement per unit time is called Velocity.…
Motion is any movement or change in position or time. Whether the movement is fast or slow, it is still in motion. There is always continuous movement in our lives, even when we think there isn’t. This is because the Earth is constantly moving around the sun, and because we are on the earth, we are moving, too. Motion has everything to do with force. Without force, there would be no movement. This is because force is needed to act upon an object to get it into motion. Movement is measured by velocity and speed. This can be miles per hour or even lightyears. Both measure the motion of something. There are also different types of motion. The first is simple movements. An example of a simple movement would be something moving in a straight line or two objects moving towards each other in a straight line. The second type of movement is a complex movement. This type of movement might be something moving at a curve or at an angle. An example of this would be throwing a ball to your…
Speed, distance, time, and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed, distance, time, and acceleration. Distance and time are two formulas that are used to determine speed and time. For example, distance equals speed multiplied with time given, time equals distance divided by speed, and speed is equals distance divided time. Speed and time are required to determine acceleration. ( This is how they are an interdependent formula.) These complex formulas will benefit you in situations , where as you are trying to find the missing equation value dealing with motion data. For example, in many situations, the problem gives information with only the values of time and distance. You are trying to solve for the speed in the given problem, so in order to determine the speed, you’d have to taken the given information and divide the time by distance. In other situations, you are trying to solve for acceleration, which only initial velocity, time, and acceleration are given. You would have to interrelate the given values and take the initial velocity and add it to the acceleration, multiplied by time, then your data and equations sum up to the final velocity. These formulas and equations, in particular, acceleration and speed, are related to Newton’s first law of motion. This is also known as inertia, inertia is the resistance of any physical object to a change in its state of motion and rest, or the ability of an object to resist any change in its motion. Objects at rest will remain at rest if both acceleration and speed are equal to zero . Newton’s first law of motion states “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” An unbalanced force is when 2 forces are…

Acceleration – A vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.…
Velocity is the speed and direction an object is travelling and it had to accelerate to get to that speed. Acceleration the rate that a change is velocity occurs, slowing down or speeding up. Everything on Earth is traveling the same speed as the Earth, so people are only able to feel the changes in velocity on Earth. For example, a helicopter is also rotating with the Earth at 1,000 mph, so it must accelerate to travel in any direction. A thought experiment also helps in debunking why objects don’t go farther when thrown in opposite directions. For instance a baseball pitcher throws the ball at 50 mph east, the direction the Earth rotates. The ball has been accelerated to 1,050 mph when combined with the Earth’s rotation. If he throws it west, the ball has been accelerated to 950 mph. The same change in velocity occurred, and because a person’s frame of reference is the Earth, they see it as the same…
Speed: Change in position over time – distance over time Velocity: Change in position and direction over time – distance and direction over time Acceleration: Change in Velocity, so a change in speed, direction or both. Example: A change in direction but not speed would be acceleration around a curve, where speed is constant but the direction changes, which means the velocity changes, which means that acceleration occurs.…
One of the topics we have discussed is acceleration, meaning that the velocity of the object being studied is changing. What causes something to accelerate? In this lab you will investigate the forces that affect the motion of objects.…
Duncan, Vinny, and Wayne are all friends working - or wasting time - the summer before senior year in high school. Duncan is the soul, Vinny the brains, and Wayne the muscle. At the end of the previous summer, Duncan tried to save a drowning girl and failed. Not being a hero has really affected his life, particularly his relationship with his girlfriend Kim. Also, he is now terrified of swimming, especially when the nightmares come back.…
