Velocity and acceleration Measuring an objects motion
speed Speed is calculated by dividing distance by time S = d/t 5.0 km/h 2.5 m/s 45 mph
velocity Velocity is the same as speed, but you tell the direction of motion in the answer. v = d/t direction 5.0 km/h north 2.5 m/s forward 45 mph backwards
velocity Find the velocity of a swimmer who swims exactly 110 m toward the shore in 72 seconds. v= ? d= 110 m t= 72 s v = d/t v = 110 m / 72 s v = 1.5 m/s forward
velocity Find the velocity of a baseball thrown 38 m from third base to first base in 1.7 s. v= ? d= 38 m t= 1.7 s v = d/t v = 38 m / 1.7 s v = 22 m/s to first base
velocity Calculate the distance in meters a cyclist would travel in 5.00 hours at an average velocity of 12.0 km/h southwest. v= 12.0 km/h d= ? m t= 5.00 h d = vt d = 12.0 km/h X 5.00 h d = 60 km d = 60, 000 m
Velocity Calculate the time in seconds an Olympic skier would take to finish a 2.6 km race at an average velocity of 28 m/s downhill. v= 28 m/s d= 2.6 km (2,600 meters) t= ? s t = d/v t = 2600 m / 28 m/s t = 93 s
acceleration Acceleration measures the change in velocity. Acceleration is measured in d/t 2 . 45.7 m/s 2 forward
acceleration Natalie accelerates her skateboard along a straight path from 0 m/s to 4.0 m/s in 2.5 seconds. What is her average acceleration? V i = 0 m/s V f = 4.0 m/s ∆t = 2.5 s a = ?
acceleration A turtle swimming in a straight line toward shore has a speed of 0.50 m/s. After 4.0 s, its speed is 0.80 m/s. What is the turtle’s acceleration? V i = 0.50 m/s V f = 0.80 m/s ∆t = 4.0 s a = ?
acceleration Marisa’s car accelerates at a rate of 2.6 m/s 2 . Calculate how long it takes her car to accelerate from 24.6 m/s to 26.8 m/s. V i = 24.6 m/s V f = 26.8 m/s ∆t = ? a = 2.6 m/s 2
