Front

How long was a stone in the air if thrown horizontally from a 2-meter-high cliff at 25.0 m/s and lands 50.0 meters away?

Back

2.00 s

Front

What is the velocity of a 60-kg cyclist racing around a circular track with a radius of 30 meters, completing one lap in 20 seconds?

Back

9.42 m/s

Front

If a person pushes a crate with a force of 30 N and the mass of the crate doubles, how does the acceleration change?

Back

Acceleration is 1/2.

Front

What is the frequency of a wave with a speed of 2.5 x 10^8 m/s and a wavelength of 0.0045 m?

Back

5.56 x 10^10 Hz

Front

Define acceleration in physics.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

Explain the concept of inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between frequency, wavelength, and wave speed?

Back

Wave speed = Frequency x Wavelength (v = fλ)

Front

What is the principle of conservation of energy?

Back

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