Which moving object has a resultant force acting on it?

On which ball is a non-zero resultant force acting?

A car of mass 1200 kg is travelling along a horizontal road. What is the acceleration of the car?

A cart has a mass of 10 kg. A boy pushes on the cart horizontally with a force of 50 N. The cart accelerates at 0.50 m/s². What is the frictional force acting on the cart

An object moves in a circle at constant speed. Which statement about the force needed on the object is correct?

A car is travelling around a circular track at a constant speed, as shown. In which direction is the resultant force on the car?

A satellite orbits the Earth at constant speed in a circular orbit. Which statement is correct?

Hooke's Law states that the force (F) needed to extend or compress an elastic object (like a spring) is directly proportional to the distance (x) it is extended or compressed, up to its elastic limit

Look at the picture!

Different weights are hung from a spring. The diagram shows the original length of the spring, and the lengths when different weights are added. The extension of the spring is directly proportional to the weight hung from it.

What is the weight of W?

The extension-load graph for a spring is shown. The unstretched length of the spring is 17.0 cm.

When an object is hung from the spring, the length of the spring is 19.2 cm.

What is the weight of the object?

Objects with different masses are hung on a spring. The diagram shows how much the spring stretches.

The extension of the spring is directly proportional to the mass hung on it.

What is the mass of object M?

A spanner is used to tighten a nut on a bicycle wheel. A force F is needed. How can the force F be reduced?

Two forces on a steering wheel acting in opposite directions. Determine direction of the Resultant moment!

A wheelbarrow has a weight W of 140 N. Which vertical force F is needed to support the wheelbarrow in the position shown?

A uniform rod rests on a pivot at its centre. The rod is not attached to the pivot. Forces are then applied to the rod in four different ways, as shown. The weight of the rod can be ignored. Which diagram shows the rod in equilibrium?
