According to Newton's first law of motion, a body at rest will remain at rest unless acted upon by:

• Another object

• A force

• Gravity

• Inertia

The property of a body to resist any change in its state of motion is known as:

• Force

• Inertia

• Momentum

• Acceleration

Which of the following is the correct expression for Newton's second law of motion?

• F = ma

• F = mv

• F = m/v

• F = mv²

In the equation F = ma, what does 'a' represent?

• Force

• Mass

• Acceleration

• Velocity

Newton's third law of motion states that for every action, there is an equal and opposite:

• Force

• Motion

• Reaction

• Acceleration

The force that opposes the motion of an object through a fluid is called:

• Gravitational force

• Frictional force

• Buoyant force

• Drag force

When a car suddenly stops, passengers lurch forward due to:

• Gravity

• Inertia

• Momentum

• Friction

Momentum is defined as the product of:

• Mass and acceleration

• Mass and velocity

• Force and time

• Velocity and time
