Real World Science: Forces Quiz

What are balanced forces?

• Forces that are equal in size but opposite in direction, resulting in no change in motion.

• Forces that are unequal in size and direction, causing an object to accelerate.

• Forces that act in the same direction, increasing the speed of an object.

• Forces that are always present in a moving object, regardless of its speed.

Why is understanding forces important in science?

• It helps in predicting weather patterns.

• It explains how and why objects move or stay still.

• It is only relevant in physics classes.

• It has no real-world applications.

What is the role of gravity in our daily lives?

• Gravity keeps us grounded on Earth and affects how objects fall.

• Gravity is responsible for the color of the sky.

• Gravity helps plants grow taller by pulling them upwards.

• Gravity has no effect on our daily activities.

What is electromagnetism?

• A force that acts at a distance and is responsible for the attraction between magnets.

• A type of energy that can be converted into heat.

• A phenomenon that occurs only in electrical circuits.

• A method of generating electricity using magnets.

What force pulls objects towards the Earth?

• Magnetism

• Friction

• Gravity

• Electromagnetism

What is pressure in terms of forces?

• Pressure is the force that acts parallel to the surface of an object.

• Pressure is the force that acts perpendicular to the surface of an object.

• Pressure is the total force acting on an object divided by its volume.

• Pressure is the force that acts in the opposite direction of motion.

What is gravitational force?

• The force that pushes objects away from each other.

• The attraction between two masses, such as the Earth and an object.

• The force that keeps objects in motion indefinitely.

• The energy produced by moving objects.

What are unbalanced forces?

• Forces that are equal in size and direction, causing no change in motion.

• Forces that are not equal in size or direction, causing a change in motion.

• Forces that act in the same direction, increasing the speed of an object.

• Forces that are always present in a balanced system.

What is an example of a balanced force?

• A person pushing a car alone with all their strength.

• Two people pushing a car from opposite sides with equal strength.

• A ball rolling down a hill.

• A book resting on a table.

What is the effect of pressure on objects?

• Pressure has no effect on objects.

• Pressure can cause deformation or changes in shape of an object, depending on the force applied.

• Pressure only affects liquids, not solids or gases.

• Pressure increases the temperature of an object without changing its shape.
