Recall that the friction force between two surfaces in contact depends on the normal force between the surfaces and the coefficient of friction. Suppose that your car is parked on a snow-covered and icy road and you are trying to pull away from the parked spot to start driving. You press the gas pedal but the tires only spin on top of the snow and ice. Which of the following strategies will help your car to grip the surface better? Increase the weight of the car by adding as many items or passengers as possible. Wait until the tires cool down because they will grip better when cold. Decrease the weight of the car by removing as many items or passengers as possible. Press both the gas pedal and the brake pedal at once.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
