Newton’s Second Law of Motion. Forces: Recap. Force: a push or a pull on an object; the result of an interaction between two objects Units: newtons (N) Types of forces: Gravity (F grav ) Friction (F fric ) Tension (F ten ) Normal Force (F norm ) Applied Force (F app )

3.1 Forces & Free Body Diagrams. Remember that Kinematics is the study of how objects move without being concerned about why they move (units 1 & 2) Dynamics explains why objects move the way they do (unit 3). What forces are acting on the ice cream cart?. Force. A push or a pull

Chapter 4 Force and Motion September 4 Newton’s first law of motion 4.1 The Concepts of Force and Net Force. Force : A force is something that is capable of changing the velocity of an object, that is, producing an acceleration.

Planetary Motions. Newton’s Laws: The New Physics. Newton’s Laws. LAW 1: A body is in natural motion when it is at rest or when moving along at a constant speed along a straight line Definition of natural motion. Newton’s Laws.

Physics 218 Lecture 7. Dr. David Toback. Before we begin. Exam 1 Next Tuesday Only on topics through Chapter 4 Homework and the Mini-practice Exam When you have 100% on all of them you will have access to a mini-practice exam

Physical Science Jeopardy!. 10- Jan noticed that when she put a tomato in water, it sank. When she put an apple in water, it floated. Why did the tomato sink while the apple floated? T he apple has more surface area than the tomato, which allowed the apple to float.

Applications of Bernoulli’s Principle. P+ ρ gy + ½ ρ v 2 = constant. If no change in height: P + ½ ρ v 2 = constant. slower speed. faster speed. more pressure. less pressure. As the speed of a fluid increases , the pressure in the fluid decreases . P α 1/v. kinetic.

Chapter 3. Forces. What is force?. A force is a push or pull Sometimes it is obvious that a force has been applied; But other forces aren’t as noticeable A force can cause the motion of an object to change. Force does not always change velocity

Q4.1. An elevator is being lifted at a constant speed by a steel cable attached to an electric motor. There is no air resistance, nor is there any friction between the elevator and the walls of the elevator shaft. The upward force exerted on the elevator by the cable is. Motor. Cable. v.

Chapter 2 Mechanical Equilibrium. Scalar Quantities Can be fully described by a magnitude and appropriate units Mass Time Temperature Area. Vector Quantities Requires a magnitude, appropriate units and a direction Displacement Velocity Acceleration Force. Vectors and Scalars.

Chapter 5. Applying Newton’s Laws. Equilibrium. An object is in equilibrium when the net force acting on it is zero. In component form, this is. The net force on each man in the tower is zero. Slide 5-13. Equilibrium. A hanging street sign with more than one force acting on it. Worst Buy.

Forces A. Newton’s 2 nd Law 1. A net force acting on an object causes the object to accelerate in the direction of the net force. 2. a = F NET / mass or a = F / m. B. Friction 1. Force that opposes motion between two surfaces in contact. 2. Amount depends on:

Projectile Motion. Projectile Motion. Feeding the Monkey (Banana Gun). Where does the zookeeper aim if he wants to hit the monkey? ( He knows the monkey will let go as soon as he shoots ! ). Feeding the Monkey. r = r 0. If there were no gravity, simply aim . at the monkey. r = v 0 t.

Forces. Forces. A FORCE is a push or a pull exerted on an object Forces can cause objects to speed up, slow down, or change direction. Force is measured in Newtons. Force. Forces come in pairs A force is a vector Forces have a magnitude and a direction. Magnitude: 5N
