Kinematics and Motion Concepts

What branch of classical mechanics defines how objects move?

• Dynamics

• Statics

• Kinematics

• Thermodynamics

Which of the following are the three concepts kinematics uses to define motion?

• Mass, Force, Energy

• Position, Velocity, Acceleration

• Distance, Time, Weight

• Momentum, Impulse, Torque

What is the key difference between speed and velocity?

• Speed includes magnitude and direction, while velocity only includes magnitude.

• Velocity includes magnitude and direction, while speed only includes magnitude.

• Speed is measured in feet per second, while velocity is measured in yards per second.

• Velocity is always greater than speed.

Why is acceleration considered a running back's most potent weapon in football?

• It allows them to maintain a constant speed throughout the game.

• It helps them change direction quickly to avoid defenders.

• It enables them to reach top speed faster than opponents.

• It increases their mass, making them harder to tackle.
