AP Physics Fall Final Exam Review

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What is the acceleration of an object in two-dimensional projectile motion at its highest point?

Back

The acceleration is still -g (downward) due to gravity, even though the vertical velocity is zero at that point.

Front

What is the relationship between horizontal and vertical acceleration in projectile motion?

Back

The horizontal acceleration is always zero, while the vertical acceleration is a constant -g (downward).

Front

What is the initial vertical velocity of a projectile fired horizontally?

Back

The initial vertical velocity is zero.

Front

What does a free body diagram (FBD) represent?

Back

A free body diagram represents all the forces acting on an object, showing their direction and magnitude.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the significance of constant speed on a hill for a car?

Back

When a car travels up a hill at constant speed, the forces acting on it are balanced, and it experiences no net acceleration.

Front

What does a constant rate of motion indicate in terms of forces?

Back

A constant rate of motion indicates that the net force acting on the object is zero.

Front

What happens to an object's motion when it is not accelerating?

Back

If an object is not accelerating, it may be at rest or moving at a constant velocity.

Front

What is the effect of gravity on a projectile's motion?

Back

Gravity causes the projectile to accelerate downward, affecting its vertical motion while maintaining horizontal motion.
