Exploring Physics Concepts

What is the magnitude of the seismic waves during an earthquake called?

• Magnitude

• Intensity

• Seismicity

• Aftershock

Describe the motion of an object moving along the x-axis with constant velocity.

• The object moves in a straight line at a constant speed without changing direction.

• The object moves back and forth along the x-axis.

• The object changes speed randomly while moving.

• The object accelerates in a curved path.

What factors affect the range of a projectile launched at an angle?

• Weather conditions

• Time of day

• Type of projectile material

• Initial velocity, launch angle, gravity, and air resistance.

How does the acceleration due to gravity influence projectile motion?

• Gravity only affects the horizontal distance traveled.

• Gravity increases the speed of the projectile indefinitely.

• Gravity causes the projectile to follow a curved path, influencing its maximum height and time of flight.

• Gravity has no effect on the path of the projectile.

Explain the difference between elastic and inelastic collisions in terms of momentum.

• Inelastic collisions result in a loss of both momentum and kinetic energy.

• Elastic collisions conserve both momentum and kinetic energy, while inelastic collisions conserve only momentum.

• Elastic collisions do not conserve momentum, while inelastic collisions do.

• Both elastic and inelastic collisions conserve kinetic energy but not momentum.

What is the formula for calculating the distance traveled by an object in free fall?

• d = g * t

• d = g * t^2

• d = 0.5 * g * t^2

• d = 0.5 * t^2

How do you determine the velocity of an object at a specific point in its motion along the y-axis?

• v(t) = dy/dt evaluated at the specific time

• v(t) = dy/dx evaluated at the specific position

• v(t) = y(t) - y(0) divided by time elapsed

• v(t) = d^2y/dt^2 evaluated at the specific time

What role does friction play in the motion of an object on a surface?

• Friction has no effect on the motion of an object.

• Friction increases speed and decreases stability.

• Friction opposes motion and enables grip on surfaces.

• Friction accelerates motion and reduces grip.

How can you calculate the time of flight for a projectile?

• T = (2 * g) / (v * sin(θ))

• T = (v * tan(θ)) / g

• T = (v * cos(θ)) / g

• T = (2 * v * sin(θ)) / g

What is the significance of the epicenter in relation to an earthquake's impact?

• The epicenter is always located at the surface of the Earth.

• The epicenter is the point where the earthquake originates underground.

• The epicenter determines the areas most affected by an earthquake's shaking and damage.

• The epicenter has no effect on the earthquake's intensity.
