KS4 Forces – Forces. What is a force?. A force is a push, pull or twist. . Say if the following are pushes, pulls or twists:. Writing on paper Typing on a keyboard Tug-of-war Unscrewing the top off a bottle Posting a letter through a door Putting on a pair of socks Turning a door handle.
Forces, Forces Everywhere. An investigation of frictional forces around us. Forces. Newton’s 2 nd law: F=m*a Weight is an example of Force Gravity is an example of Acceleration Forces can be described by the direction in which the acceleration acts Forces acting on surfaces Normal Force.

Forces. Mechanics. Kinematics . Dynamics. Describes motion. The forces that cause motion. Forces. Elementary Definition: Force – a push or a pull Not totally accurate though. Forces. True Physics Definition: Force – any action that can cause a change of motion in an object. Forces.
FORCES. Which vehicle exerts a greater force ― the tow truck or the car?. What is a force?. A push or a pull When one object pushes or pulls another object, you say that the first object exerts a force on the second object. Let’s practice. What forces are at play around you?.
FORCES. Gravity is a force that exists between all objects in the universe - based on their masses and the distance between them … Do you remember the formula??. Gravity . F = G m 1 m 2 d 2. G = 6.67 X 10 -11 Nm 2 /kg 2 (gravitational constant)

Forces. Answers. #1. Known mass = 40 kg g Earth = 9.8 m/s 2 g Jupiter = 25.0 m/s 2 mass is constant…. #2. Known m = 23.0 g F = 3.00 N force is kg m/ s 2 , so, have to convert to kg F = ma. #3. Known m arrow = 29.0g needs to be in kg d = 7.00 cm needs to be in m
