Natural forces constantly acting on your vehicle, influencing its movement, balance, and weight

• Laws of Nature

• Man-made forces
• Supernatural forces
• Artificial forces

All of these are laws of nature: Gravity, Friction, Inertia, Centrifugal, Centripetal, Momentum, Force of impact

• True

• False

natural force that constantly attracts objects toward the Earth and affects the object’s weight.

• Magnetism
• Friction
• Gravity
• Inertia

Center of Gravity

• balance point for the object. It's the point at which the upper and lower vehicle weight is balanced.

• resistance that one surface or object encounters when moving over another.

• grip of a tire on a road

• object’s tendency to resist any change in its state of motion

Friction

• balance point for the object. It's the point at which the upper and lower vehicle weight is balanced.

• resistance that one surface or object encounters when moving over another.

• grip of a tire on a road

• object’s tendency to resist any change in its state of motion

Traction

• balance point for the object. It's the point at which the upper and lower vehicle weight is balanced.

• resistance that one surface or object encounters when moving over another.

• grip of a tire on a road

• object’s tendency to resist any change in its state of motion

Inertia

• balance point for the object. It's the point at which the upper and lower vehicle weight is balanced.

• resistance that one surface or object encounters when moving over another.

• grip of a tire on a road

• object’s tendency to resist any change in its state of motion

The lower the center of gravity, the more stable the vehicle, and the less likely it is to (hint: action that starts with r)

This scenario demonstrates what law of nature?

if you were to get into an accident, your safety belt would prevent this from pushing you forward when the vehicle has stopped.

• Law of motion
• Law of friction

• Law of inertia
• Law of gravity

__ forces push things away from the center where as __ forces pull them

• Gravity, Magnetism
• Centrifugal, Centripetal
• Friction, Tension
• Inertia, Elasticity
