Understanding Projectile Motion

Uniformly Accelerated Motion is moving in two dimensions namely the _____________ and __________________ dimension.

In UAM, an object that is moving horizontally has a ____________ velocity.

How many equations we will used to solve for UAM problems?

When the object is moving vertically upward, the velocity _____________.

When the object is moving vertically downward, the velocity _____________.

Putting a (-) negative sign in the value of an object means the object is moving or accelerating ____________.

The rate at which velocity changes is called 

• motion
• average speed
• instantaneous speed
• acceleration

g is defined as

• the fastest that an object can fall
• acceleration of objects moving vertically
• acceleration caused by gravity
• the force of gravity on an object

2. In a body exhibiting a uniformly accelerated motion, which of the following quantities is constant?

• A. acceleration

• B. speed

• C. velocity

• D. time

As the saying goes " Anything that goes up, goes down.", this is due to what force on Earth?

• Friction

• Gravity

• Momentum

• None of the above
