Ramps and Inclines - APlusPhysics
Supplies Needed 1. Materials to make ramps; you can use cardboard or wood planks! 2. Variety of toy cars 3. Variety of textured materials to create friction – There are so many ideas! We used a hand towel, sandpaper, and rubber grippy mats. You could also use foil or parchment paper, a piece of rug, or even dirt. 4. … See more Allow your kids to explore the bare ramp as they wish. They are going to be super excited to play, so it is often best to let them explore the activity freely for a bit first! You can also … See more Young kids learn by exploring, observing, and figuring out the way things work by experimenting. Exploring ramps and friction encourages all of the above. Kids will learn that friction can be two surfaces rubbing against one … See more WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s. WebMay 3, 2015 · As per the answer to the question (modified); speed at the bottom will not be dependent on the angle of the ramp, provided that. There is no friction. The height of the topmost point on the ramp from the ground is same. As Mr Nasu mentioned if you have a ramp with hinge at the bottom, then the length of the ramp will be constant and height ... event company uk
