A car moves with a speed of 30 metres per second calculate the distance travelled in 30 seconds

Explain what relative weight is and why it is important to the calculation of atomic mass.

1. How does potential energy differ from kinetic energy?

If a 1500 kg car can accelerate from 35 km/h to 55 km/h in 3.2 s, how long will it take to accelerate from 55 km/h to 100 km/h? assume the power stays the same, and neglect frictional losses

Amusement Park Ride At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.

The amount or the strength of force is called its

An airplane in flight has a pressure difference between the lower and upper wing surface; this provides an upward force that balances the weight of the plane.

When creating a new document from a template you have two options, create a new document or create a new template.

Why does momentum have a direction?

What is the difference between weight and mass?
