... to measure the size of a force. Show a spring-type force scale for comparison. The key idea to bring across in connection with Newton’s first law is that a force is needed to cause any change in motion—in speed or direction. The concept of a net force and an external force may have to be explained. ...

... NOTE: This is not required for A2 AQA Physics Consider an object moving at constant speed, v from point A to point B along a circular path of radius r. Over a short time period, δt it covers arc length, δs and sweeps out angle, δθ. As v = δs / δt then δs = v δt. The velocity of the object changes in ...

Problem: 2nd Law and Pulleys (CM-1993)
... In the absence of air friction, an object dropped near the surface of the Earth experiences a constant acceleration of about 9.8 m/s2. This means that the (A) speed of the object increases 9.8 m/s during each second (B) (B) speed of the object as it falls is 9.8 m/s (C) object falls 9.8 meters durin ...

... 11) If we double the mass of an object in motion, what would happen to its acceleration? Doubling the mass will divide the acceleration by two 12) If we apply three times the force to an object as the original force applied, what would happen to the object’s acceleration? Multiplying the force by 3 ...
