AP Physics Midterm Review 2023

Front

What happens to the normal force as the angle of the incline increases?

Back

The normal force decreases.

Front

If the speed of a 0.50kg cart is doubled from 0.40m/s, what happens to its inertia?

Back

The inertia remains unchanged.

Front

What is the formula for the acceleration of a system with two blocks under a force F?

Back

A = F/3m.

Front

If an object is stationary, what can we say about the forces acting upon it?

Back

The forces are balanced.

Front

What is the trajectory of a projectile fired at an angle with initial velocity V0?

Back

The vertical components of velocity and acceleration change over time.

Front

Define inertia in the context of physics.

Back

Inertia is the resistance of an object to change its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

Explain the concept of balanced forces.

Back

Balanced forces occur when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the formula for calculating gravitational potential energy?

Back

Potential Energy (PE) = mass × gravity × height.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
