Discuss the concept of projectile motion in classical mechanics.

• Projectile motion results in a straight-line trajectory.

• Projectile motion involves analyzing the motion of objects underwater.

• Projectile motion only considers the horizontal component of motion.

• Projectile motion in classical mechanics involves analyzing the motion of objects thrown into the air, considering both horizontal and vertical components affected by gravity, resulting in a parabolic trajectory.

• Velocity is the same as speed.

Explain the concept of torque in classical mechanics.

• Torque is the measure of the force that can cause an object to rotate around an axis.

• Torque is a measure of temperature in classical mechanics.

• Torque is a measure of pressure in classical mechanics.

• Torque is a measure of speed in classical mechanics.

• A plane taking off from a runway

The mass of an object divided by its volume is its _______.

What is the formula for calculating acceleration?

• Acceleration = Velocity / Time

• Acceleration = Mass / Force

• Acceleration = Force / Mass

• Acceleration = Distance / Time

In what units is speed typically measured?
