Motion in Two Dimensions

Front

Acceleration results from the vector difference of

Back

velocity vectors

Front

A measurement of 15 m/s² is a measure of

Back

acceleration

Front

Any system that experiences an acceleration must show a(n)

Back

change in velocity

Front

If a system's acceleration is uniform, then

Back

its average and instantaneous accelerations are the same

Front

When a bullet is fired at an upward angle, its vertical velocity is nonzero

Back

At the moment it is fired.

Front

Projectile range is a function of

Back

initial velocity, time of flight, initial height.

Front

If a car maintains a steady speed of 120 km/h when rounding a 200 m long curve, how long will it take to round the curve?

Back

6.00 s

Front

The perspective from which an object is viewed or its motion is described is called its

Back

Frame of reference.

Front

A vector with a magnitude of 0 units is called the

Back

Zero vector.

Front

When a ballistic projectile is launched, it is assumed that only gravity acts on it.

Back

True
