The normal component of acceleration always points INWARD to the path. The tangential component direction depends on how the point P is changing in speed. If the speed is INCREASING, angle θ between ...

Treat acceleration as a vector when there is another vector quantity, such as velocity or force, involved in a question. Forces need a size and direction, eg \(300 N\) to the left.

GCSE Combined Science Motion and forces learning resources for adults, ... Resultant forces will cause acceleration, ... Momentum can be thought of as a combination of mass and velocity.

In a valid follower motion, the velocity and acceleration will remain continuous throughout the cycle — otherwise the device produces an impossible, infinite amount of jerk.

Apply transport theorem to differentiate vectors, derive frame-dependent velocity and acceleration vectors, and solve kinematic particle problems Translate between sets of attitude descriptions Apply ...
