What is Newton's second law of motion?

• The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass
• Only the force applied to an object determines its acceleration

• The energy of an object is directly proportional to its mass and speed
• The speed of an object is directly proportional to its acceleration
• The distance traveled by an object is directly proportional to its time of travel

Why is the relationship between force, energy, and speed of travel crucial for road safety?

• The greater the force or speed of a vehicle, the higher the risk of accidents
• The greater the force or speed of a vehicle, the lower the risk of accidents
• The relationship does not affect road safety
• The relationship between force, energy, and speed is only relevant for air travel
• The relationship between force, energy, and speed is only relevant for water travel

What are the two main types of energy?

• Kinetic energy and potential energy
• Mechanical energy and thermal energy
• Electrical energy and chemical energy
• Gravitational energy and nuclear energy
• Solar energy and wind energy

What is the formula for calculating speed?

• Speed = distance/time
• Speed = force x mass
• Speed = energy/mass
• Speed = acceleration x time
• Speed = work/distance

What are some forces that can affect objects in motion?

• Air resistance, friction, gravity, lift, drag, momentum, and inertia
• Velocity, acceleration, work, power, and momentum
• Electricity, magnetism, buoyancy, and thermal energy
• Pressure, temperature, density, and viscosity
• Tension, compression, torsion, and shear

How does the amount of force applied to an object affect its acceleration?

• The amount of force applied is directly proportional to the acceleration
• The amount of force applied is inversely proportional to the acceleration
• The amount of force applied does not affect the acceleration
• The amount of force applied determines the object's mass
• The amount of force applied determines the object's speed

What is the relationship between the kinetic energy of an object and its speed and mass?

• The kinetic energy is directly proportional to both the object's speed and mass
• The kinetic energy is inversely proportional to both the object's speed and mass
• The kinetic energy is directly proportional to the object's speed and inversely proportional to its mass
• The kinetic energy is inversely proportional to the object's speed and directly proportional to its mass
• The kinetic energy is only determined by the object's speed
