Force and Resultant Force

What is the definition of force?

• Force is the temperature of an object

• Force is the speed of an object

• Force is the color of an object

• Force is a push or pull upon an object resulting from the object's interaction with another object.

Name two types of forces.

• Push forces and pull forces

• Contact forces and non-contact forces

• Frictional forces and tension forces

• Gravitational forces and electromagnetic forces

What is the formula to calculate resultant force when forces are acting in the same direction?

• Resultant force = Force1 + Force2 + ... + ForceN

• Resultant force = Force1 * Force2 * ... * ForceN

• Resultant force = Force1 / Force2 / ... / ForceN

• Resultant force = Force1 - Force2 - ... - ForceN

What is the formula to calculate resultant force when forces are acting in opposite directions?

• Resultant force = |F1 - F2|, where F1 and F2 are the forces acting in opposite directions

• Resultant force = F1 * F2

• Resultant force = F1 / F2

• Resultant force = F1 + F2

What is gravitational force?

• Gravitational force is the force of attraction between two objects with mass.

• Gravitational force is the force of attraction between two objects with mass.

What is frictional force?

• Frictional force is the force that opposes the motion of an object when it is in contact with another object or surface.

• Frictional force is the force that attracts objects to each other

• Frictional force is the force that causes objects to float in the air

• Frictional force is the force that accelerates the motion of an object

What is the unit of force?

• kilogram

• meter

• joule

• newton (N)

Explain the concept of balanced forces.

• Balanced forces occur when the net force on an object is negative, causing the object to slow down and eventually stop.

• Balanced forces occur when the net force on an object is zero, causing the object to remain at rest or continue moving at a constant velocity.

• Balanced forces occur when the net force on an object is unbalanced, causing the object to move in a straight line.

• Balanced forces occur when the net force on an object is maximum, causing the object to accelerate rapidly.

Explain the concept of unbalanced forces.

• Unbalanced forces refer to forces that cause a change in an object's motion or shape, resulting in acceleration or deformation.

• Unbalanced forces are only relevant in theoretical physics and have no practical applications.

• Unbalanced forces only occur in outer space, where there is no gravity to counteract them.

• Unbalanced forces refer to forces that cancel each other out, resulting in no change in an object's motion or shape.

Calculate the resultant force when a 10N force is acting to the right and a 5N force is acting to the left.

• 15N

• 5N

• 2N

• 7N
