skateboard out of his way. Calculate the initial acceleration A solo arctic adventurer pulls a string of two toboggans of supplies across level‚ snowy ground. The toboggans have masses of 95kg and 55kg. Appling a force of 165N causes the toboggans to accelerate at 0.61m/s2. Find the tension in the rope attached to the second toboggan. A 75kg man is standing on a scale in an elevator when the elevator begins to descend with an acceleration of0.66 m/s2. What is the reading on the scale while

Physics C-110 Module 1 Chapter 1 1. What is science? Science is a body of knowledge that is ever changing. It is made up of not only facts but also theories that are made up of well-tested hypotheses. 2. Distinguish among the scientific fact‚ hypothesis‚ law and theory As stated above‚ a theory is made up of well-tested hypotheses‚ which in themselves are well educated guesses yet to be proven. A fact is something that can change over time even though it was agreed upon by knowledgeable

Projectile Motion Lab Report Objectives: This laboratory experiment presents the opportunity to study motion in two dimensions‚ projectile motion‚ which can be described as accelerated motion in the vertical direction and uniform motion in the horizontal direction. Procedures and Apparatus: |Rubber Ball |White sheets of papers | |Metal Track |Water | |Books |Table | |Meter-stick

these two components of motion can be discussed separately. The goal of this part of the lesson is to discuss the horizontal and vertical components of a projectile’s motion; specific attention will be given to the presence/absence of forces‚ accelerations‚ and velocity. A basketball being thrown up to hoop fits. When shooting‚ ball follows the same direction as a projectile in motion. Doing free throw is a projectile. It is related to a projectile as the force exerted upon the basketball is

Point - a point against which position is measured. B: Vector Quantity - a physical measurement that contains directional information. C: Scalar Quantity - a physical measurement that does not contain directional information. D: Acceleration - the time rate of change of an objects velocity. E: Free Fall - the motion of an object when it is falling solely under the influence of gravity. 2. No. Motion depends on the reference point that is used. 3. That depends on the

opens‚ click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When the ball is stopped there isn’t any changes in the placement of the ball. This means that there is zero velocity at that time. 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? The green arrow represents

| Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature | Example: displacement‚ velocity‚ acceleration‚ force | Distance and displacement Distance is defined as the ground covered by a moving object during its motion. Its SI unit is metre (m). It has only magnitude‚ but no direction. Distance can never be negative. The minimum value of distance
Premium Velocity Physical quantities Classical mechanics
Kinematics is one of the topics under dynamics. Kinematics describes motion without regard to its causes. In this experiment‚ kinematics focuses in one dimension: a motion along a straight line. This kind of motion‚ involves velocity‚ displacement‚ and acceleration with regards to time. The objectives of the experiment are to draw the displacement versus time graphs and velocity versus time graphs for uniform motion and uniformly accelerated motion‚ and to determine one’s normal reaction time and his reaction

CHECK ACTIVITY ON MOTION 1. A car speeds up from 40 km/h to 55 km/h to overtake a truck. If this requires 15 s‚ what is the (a) acceleration and (b) distance traveled by the car? 2. Albert is riding his scooter at a velocity of 80 km/h when he sees an old woman crossing the road 45 m away. He immediately steps hard on the brakes to get the maximum acceleration of 7.5 m/square second. how far will he go before stopping? Will he hit the old woman? 3. the time a male bungee jumper if freely
