1. What is the velocity of a motorcycle that is traveling 10 meters in 3.5 seconds? 2. A high school track runner starts at the 50-meter line and runs to the 250-meter line in 12 seconds. What is their velocity? 3. Calculate the acceleration of Josh riding his bike in a straight line that speeds up from 4 m/s to 6m/s in 5 seconds. 4. Kaya is slowing down on her skateboard. She starts at a speed of 5.5 m/s and slows to 1.0 m/s over a time of 3 seconds. What is Kaya's acceleration? 5. A man hits a golf ball (0.3 kg) which accelerates at a rate of 20 m/s?. What amount of force acted on the ball? 6. A worker drops a hammer off the roof of a house. The hammer has a mass of 11 kg, and gravity accelerates it at the usual 9.81 m/s2. How much force does the Earth apply to the hammer?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
