AP Physics 1 Short Review #2

Front

What is the relationship between the vertical component of velocity of rocks launched at the same speed from different angles just before hitting the ground?

Back

The vertical component of velocity just before impact is influenced by the launch angle. For rocks launched at the same speed, those launched vertically will have the greatest vertical velocity, while those launched at an angle will have a lesser vertical component. Specifically, if two rocks are launched at the same speed but different angles, the one launched vertically will have a greater vertical component than the one launched at a shallower angle.

What is kinetic energy and how does it change in different scenarios?

Front

How can force vs. time and force vs. position graphs be used to determine the speed of a cart after it rebounds?

Back

Both force vs. time and force vs. position graphs can provide information about the impulse experienced by the cart, which relates to its change in momentum. The area under the force vs. time graph gives impulse, which can be used to find the final speed after rebounding.

What is the moment of inertia and how does it affect angular acceleration?

How is gravitational potential energy calculated and what factors influence it?

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. In a closed system, the total energy remains constant.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved, but kinetic energy is not; some energy is transformed into other forms, such as heat or sound.

Front

What is projectile motion and what factors affect its trajectory?

Back

Projectile motion is the motion of an object thrown into the air, affected by gravity and air resistance. The trajectory is influenced by the initial velocity, launch angle, and height.
