If a car travels 100 meters in 10 seconds, what formula would you use to calculate its velocity?
If a car travels 100 meters in 10 seconds, what formula would you use to calculate its velocity?
- Velocity = Distance * Time
- Velocity = Time + Distance
- Velocity = Distance / Time (correct)
- Velocity = Time / Distance
What is the relationship between force and acceleration, according to Newton's Second Law?
What is the relationship between force and acceleration, according to Newton's Second Law?
- Acceleration is directly proportional to force and inversely proportional to mass. (correct)
- Force is directly proportional to area.
- Acceleration is inversely proportional to force.
- Force is inversely proportional to mass and acceleration.
A soccer ball is kicked. According to Newton's Third Law, what occurs?
A soccer ball is kicked. According to Newton's Third Law, what occurs?
- The ball exerts an equal and opposite force back on the foot. (correct)
- The foot exerts a greater force on the ball than the ball exerts on the foot.
- The ball accelerates until an external force stops it.
- There is no reaction since the action is only on the ball.

Study Notes
- Formulas
MRU (Uniform Rectilinear Motion)
- Velocity = Distance / Time
- Distance = Velocity * Time
- Time = Distance / Velocity
Pressure
- Pressure = Force / Area
- Pressure is measured in Pascals [Pa]
Forces
- Weight = Mass * Gravity
- Gravity = 9.8 m/s
- Force = Mass * Acceleration
- Acceleration = Force / Mass
- Mass = Force / Acceleration
Newton's Laws
- 1st Law - Law of Inertia: An object at rest remains at rest, and an object in motion continues in motion with constant velocity unless acted upon by an external force.
- 2nd Law - Law of Force and Acceleration: The acceleration of an object is directly proportional to the applied force and inversely proportional to its mass.
- 3rd Law - Law of Action and Reaction: For every action, there is an equal and opposite reaction.
