Figure 20 shows a person trying to lift a large rock using a metal bar. The rock weighs 1800 N. The person can only produce a downwards force of 600 N. The person cannot lift the rock. (i) Explain, using calculations, why the person cannot lift the rock. (3)
Assuming the baseball landed 100 meters away from home plate, how much force did the player use to hit the ball? Explain the following situations with diagrams and labels.
Work Done & Energy Transfer 3 QP. Summary notes, revision videos and past exam questions by topic for AQA Physics GCSE Topic 5 - Forces.
Use the equation in the box to calculate the work done by the powerlifter. work done = force applied × distance moved in direction of force Show clearly how you work out your answer and give the unit.
30 sie 2017 · In this topic, we will see an application of Newton’s Second Law in 5 selected cases of Elevator movement, which will help us to solve elevator problems in Physics with ease. From Newton’s Second Law, we can derive the equation of Force. If F is the net force applied on an object of mass m and the mass moves with an acceleration ‘a ...
(c)€€€€€The drag lift pulls the skier with a constant resultant force of 300N for a distance of 45 m. Use the following equation to calculate the work done to pull the skier up the slope. €€€€€€€€€€€€€€€€€€€€€€€€€work done = force × distance
21 lis 2023 · Step 1: Draw a vector triangle of the resolved forces. Step 2: Calculate the vertical component of the lift force.
