Applied English for Science

What does a horizontal line on a velocity-time graph represent?

• Increasing speed

• Constant velocity

• Changing direction

• Object at rest and move

Which quantity describes how fast an object moves and in which direction?

• Speed

• Velocity

• Displacement

• Acceleration

What is the difference between displacement and distance?

• Displacement is always greater than distance

• Distance has direction, displacement does not

• Distance is a scalar, displacement is a vector

• They are the same in all cases

According to Newton's First Law, what happens to an object with no net force acting on it?

• It accelerates

• It remains at rest or moves at constant velocity

• It increases in mass

• It changes direction

What is inertia?

• A force that resists motion

• The tendency of an object to resist changes in motion

• A form of energy

• A type of acceleration

What does Newton's Second Law explain?

• The relationship between mass and inertia

• The conservation of energy

• How force, mass, and acceleration are related

• The gravitational attraction between two objects

What is energy?

• A force that pushes objects

• The speed of an object

• A type of motion

• The ability to do work

Which of the following is an example of potential energy?

• A stretched spring

• A rolling ball

• A moving car

• A flowing river

What does power measure?

• The total force used

• The time taken to move

• How quickly work is done

• The energy stored

What does Coulomb’s Law describe?

• The electric force between two charges

• The magnetic force between poles

• The gravitational force between planets

• The resistance of a circuit
