Introduction to Uniformly Accelerated Motion with Examples of Objects in UAM

The video tutorial introduces uniformly accelerated motion (UAM), explaining that it involves constant acceleration. Various real-world examples are provided, acknowledging their imperfections. The tutorial covers four key UAM equations and identifies five variables involved. It emphasizes using base SI units for accuracy and explains how knowing three variables allows calculation of the remaining two. The session concludes with a recap and a promise to solve an exam problem in the next lecture.

What is the defining characteristic of an object in uniformly accelerated motion?

• It moves with a constant speed.

• It moves with a variable speed.

• It moves with a constant acceleration.

• It moves with a changing acceleration.

Which of the following is NOT an example of uniformly accelerated motion?

• A ball rolling down an incline.

• A person falling from a plane.

• A bicycle on which brakes are applied.

• A car moving at a constant speed.

How many equations are there for uniformly accelerated motion?

• Four

• Three

• Five

• Two

Which of the following is NOT one of the five variables in the UAM equations?

• Velocity final

• Acceleration

• Mass

• Displacement

What is the recommended unit system to use when solving UAM problems?
