Acceleration can be affected by several factors, including the force applied to an object, the mass of the object, and any external forces such as friction or air resistance. The direction of the force also plays a role in determining the direction of acceleration. ...
A 25 kg box slides down a 23.0 ◦ ramp with an acceleration of 1.37 m/s Find the coefficient of kinetic friction between the box and the ramp.相关知识点: 试题来源: 解析 力分解为:运动方向和垂直运动方向; 垂直方向受力:此方向加速度0,受力平衡,m*g*(cos23)= Fn 支持力运动方向受力:...
about 4 g; (d) The speed of the swing is too large. At the given velocity at the bottom of the swing, there is enough kinetic energy to send the child all the way over the top, ignoring friction.
Nora has a Master's degree in teaching, and has taught a variety of elementary grades. What makes objects go faster or slow down? Help your middle school students understand the physics of acceleration and deceleration with these engaging activities. ...
If a body falls freely under the influence of Earth's gravitational field, what generalization can you make concerning the sum of its potential and kinetic energies at any given instant? (Assume there is no air resistance.) How does a parachute...
CONSTITUTION:The acceleration of an acceleration/deceleration control part is calculated when a velocity-acceleration curve Ac obtained by subtracting a kinetic friction component from a torque curve of a servo motor touches the velocity-acceleration curves (Lc, L) of the answer of the motor given ...
If mass m moves with the acceleration 'a' on applying the external force then according to Newton's second law of motion; {eq}F_{ext} = ma {/eq} Answer and Explanation:1 Given: {eq}m = 1\,kg. {/eq} {eq}M = 4\,kg. {/eq} ...
If it was not for loss of energy via friction through air resistance, the cycle of potential energy to kinetic energy and back to potential energy would just continue indefinitely (Fig. 1.1.9d). Sign in to download full-size image Fig. 1.1.9d. The left image illustrates the principles ...
and many more concepts from our website Physicscalc.Com. a = ( (100 km/h) - (0 km/h)) (1000 m/km) / (3600 s/h)) / (3 s) = 9.26 (m/s2) or close to acceleration of gravity 1 g = 9.81 (m/s2) . Use the normal force to calculate the force due to kinetic friction: ...
