Revision of P2 Part I - Complete tasks 1-17 by Mr V

Task 1 - Acceleration calculations

MrVieito — 2015-03-01 09:18:40 UTC

Find the acceleration of a cat whose velocity goes from 2 m/s to 6 m/s in 5 s.

Task 3 - Velocity-time graphs

MrVieito — 2015-03-01 09:20:34 UTC

Draw and label the graph then write out a guide to interpreting a velocity time graph. e.g. "A straight line on a velocity-time graph represents..."

Task 2 - Distance-time graphs

MrVieito — 2015-03-01 09:23:11 UTC

Draw and label the graph then write out a guide to interpreting a distance-time graph. e.g. A straight line on a distance-time graph represents.

Task 4 - Velocity-time graphs II

MrVieito — 2015-03-01 09:25:39 UTC

Calculate the acceleration of the cyclist between 60-80 seconds (calculate the gradient) and the distance travelled between 0-60 seconds (distance travelled = area under the graph).

Task 5 - What is the resultant force? Write a definition.

MrVieito — 2015-03-01 09:29:02 UTC

What is the resultant force on the car?

Task 8 - What is the motion of this boat? Accelerating or not? Why?

Task 6 - Resultant force and motion - answer in full sentences

MrVieito — 2015-03-01 09:31:57 UTC

What happens to a stationary object when there is no resultant force acting on it?

What happens to a stationary object when there is a resultant force acting on it?

Task 7 Resultant force and motion - full sentences please.

MrVieito — 2015-03-01 09:39:59 UTC

What happens to a moving object when there is no resultant force acting on it?

What happens to a moving object when there is a resultant force acting on it?

Task 9 - F=ma

MrVieito — 2015-03-01 09:42:20 UTC

If a moving object has a resultant force act on it it is accelerated in the direction of the resultant force.

A car with a mass of 900 kg accelerates from rest with an acceleration of 2.5 m/s2. Calculate the driving force provided by the car’s engine.

Task 10 F = ma

MrVieito — 2015-03-01 09:48:57 UTC

Which car produces the greater force?

Task 11 - Use the equation...

MrVieito — 2015-03-01 09:50:50 UTC

...to calculate the weight of a man with a mass of 68kg.

And calculate the mass of a car with a weight of 3280N

Task 12 - Terminal velocity

MrVieito — 2015-03-01 09:54:01 UTC

Use the graph to explain how an object reaches terminal velocity. e.g. "As the object begins to fall..."

Task 13 - Terminal velocity

MrVieito — 2015-03-01 09:57:41 UTC

In both diagrams the forces are balanced but the speed is different. How does the resistance force arrow change when the parachute is opened and what change in motion does this produce

Title 14 - Stopping distances

MrVieito — 2015-03-01 10:01:38 UTC

A man is driving along and sees a hazard on the road, applying the brakes for an emergency stop. His thinking distance is 11 m and his braking distance is 32 m. What’s his stopping distance

Task 15 - Explain how thinking distance is affected by;

MrVieito — 2015-03-01 10:03:42 UTC

Your speed

Whether you've had alcohol or drugs

Task 16 - Explain how braking distance is affected by;

MrVieito — 2015-03-01 10:04:41 UTC

Tyres

Weather conditions

Task 17 - Hooke's Law

MrVieito — 2015-03-01 10:07:51 UTC

An old-fashioned set of weighing scales consists of a bowl suspended from a spring with spring constant k = 69 N/m. Some flour is placed in the bowl, causing the spring to extend by 0.027m. How much does the flour weigh?
