Physics Quiz on Force

What is the SI unit of force?

• Joule

• Newton

• Watt

• Pascal

Force can be described as:

• A push only

• A pull only

• Either a push or a pull

• Neither a push nor a pull

Which of the following is NOT typically affected by a force?

• An object's motion

• An object's direction

• An object's mass

• An object's speed

The formula F = ma is known as:

• Newton's First Law

• Newton's Third Law

• The Law of Conservation of Energy

• Newton's Second Law

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

• Momentum

• Mass

What is the acceleration of an object with a mass of 5 kg when a force of 10 N is applied to it?

• 2 m/s²

• 0.5 m/s²

• 50 m/s²

• 15 m/s²

A force of 100 N gives an object an acceleration of 20 m/s². What is the mass of the object?

• 5 kg

• 2000 kg

• 0.2 kg

• 120 kg

Which of the following would NOT increase the force applied to an object?

• 750 N

• 3000 N

• 1502 N

• 3750 N

If a force of 50 N causes an acceleration of 5 m/s² on an object, what would be the acceleration if the force was doubled to 100 N?

• 2.5 m/s²

• 10 m/s²

• 25 m/s²

• 7.5 m/s²
