dear nath there is a formula for speed i think you will nedd to know it ..learn it

a mouse startin from rest reaches of 0.08 m/s in 35 secs how far does it travel in that time

explain how to calc speed from a distance time graph

what is the acceleration of a soggy pea flicked from rest to a speed of 14 m/s in 0.4 secs

explain for to find speed distance and acceleration from a speed time graph.....jesus nath

explain the differnce between mass and weight..and what is the formula for weight

use mind map to label the forces acting on a stationary owl sat on a stationary rock

describe the effect on the top speed of a car of adding a roof box..and you have to explain the answer

describe how air resistance is affected by speed

what is terminal speed ..what 2 main factors affect the amount of drag on a falling object

what actor is famous for saying ...i feel the need ...the need for speed

if an object has zero resultant force on it , can it be moving ? can it be accelerating ?

A force of 30N pushes a trolley of mass 4kg. What will be its acceleration?

What are the two different parts of overall stopping distance of a car?

List all the factors which affect each of the two parts of stopping distance?

How does thinking distance change as speed increases

If speed doubles, what happens to the braking distance?

The same ferret is hit by a speeding vole with a force of 70N for 0.5s. Calculate the ferret's change in momentum

Explain how seat belts, crumple zones and air bags are useful in a crash.

How do ABS brakes make driving safer?

A crazy dog drags a branch 12m over the next-door neighbour's fron lawn, pulling with a force of 535 N. How much work was done?

Calculate the increase in gravitational potential energy when a box of mass 12kg is raised by 4.5m (g=10N/kg

Find the kinetic energy of a 78kg sheep moving at 23m/s.

How does the kinetic energy formula explain the effect of speed on the stopping distance of a car?
