kinematics

what is kinematic

• branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved

• a force

• a solution

the unit we measure time is in ___.

• m/s

• m

• m/s^2

• s

A car accelerates uniformly from rest at 3.2m/s ²

when the car traveled a distance of 40 m it’s speed will be

• 12.5 m/s

• 8.0m/s

• 16m/s

• 128m/s

an object can be moving for 10 seconds and still have zero displacement.

• true

• false

a car is NOT accelerating if it is moving

• at constant velocity

• only as influenced by gravity

• in a circle

• at increasing speed

a tiger travels 96 m in 8s. what is his velocity over the interval

• 0.04m/s

• 25m/s

• 225m/s

• 12m/s

what is the formula to calculate speed.

• S=t/d

• S=t/d

• S=t x d

• S=d x t
