Kinemaths

From the graph above:

What value can be deduced from area under graph?

From the graph, what is the acceleration at t = 2.0 s?

(state value only; without unit)

Determine the total distance travelled shown by the graph.

A stone is released from rest and falls freely under gravity. By using g = 10 m s^-2, find the speed of the stone after 2 s. (state value only ; without unit)

A stone is released from rest and falls freely under gravity. By using g = 10 m s^-2, find the time taken for the stone to fall a distance of 45 m from its initial position.

(state value only ; without unit)

A stone is released from rest and falls freely under gravity. By using g = 10 m s^-2, find the distance travelled by the stone with initial speed 30 ms^-1 until it reaches 40 m s-¹.

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

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

a car is NOT accelerating if it is moving

• at constant velocity

• only as influenced by gravity

• in a circle

• at increasing speed

A cheetah travels 75 m in 3 s. What is her velocity?

• 225m/s

• 25m/s

• 0.04m/s
