Physics Basics

What is force?

• Force is a type of energy

• Force is a scientific theory

• Force is a form of matter

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

Define energy in physics.

• Energy is the ability to control time.

• Energy is the ability to create matter.

• Energy in physics is the ability to do work.

• Energy is the ability to store matter.

What is motion in the context of a moving car?

• Motion is the change in position of a car over time.

• Motion is the absence of change in position of a car.

• Motion is the same as rest for a car.

• Motion is the speed of a car.

Explain the concept of gravity using a real-world scenario.

• Gravity is the force that pulls objects towards the center of the Earth.

• Gravity is the force that causes objects to fall upwards.

• Gravity is the force by which a planet attracts objects towards its center.

• Gravity is the force that repels objects away from each other.

What is friction in a real-world scenario?

• Friction is the force that helps cars stop on icy roads.

• Friction is the force that makes it difficult to slide on a wet floor.

• Friction is the force that allows a climber to grip a rock wall.

• Friction is the force that attracts a magnet to metal.

How is speed defined in physics?

• Speed is defined as the rate at which an object covers distance.

• Speed is defined as the temperature of an object.

• Speed is defined as the color of an object.

• Speed is defined as the weight of an object.

Which law states that an object at rest will stay at rest unless acted upon by an external force?

• Boyle's Law

• Einstein's Theory of Relativity

• Archimedes' Principle

• Newton's First Law of Motion

What is the SI unit of force when Abigail pushes a box?

• Kilogram

• Newton (N)

• Joule

• Meter

How does friction affect the motion of a car on a rainy road?

• Friction accelerates the car's motion on a rainy road

• Friction has no impact on the car's motion on a rainy road

• Friction causes the car to move in a circular path on a rainy road

• Friction opposes the car's motion on a rainy road by acting in the opposite direction.

How does air resistance affect the motion of a falling object?

• Air resistance accelerates the falling object

• Air resistance has no impact on the falling object

• Air resistance causes the falling object to fall faster

• Air resistance opposes the motion of the falling object by acting in the opposite direction
