Quiz on Newton's Laws of Motion

According to Newton's first law of motion, an object's motion will not change unless acted upon by:

• Balanced forces

• Unbalanced forces

• Gravitational forces

• Magnetic forces

An object's motion will remain the same when what type of force is applied?

• Unbalanced forces

• Balanced forces

• Frictional forces

• Tension forces

If a balanced force is applied to an object moving at a velocity of 2 m/s, the moving object's motion:

• Speeds up

• Slows down

• Remains the same

• Stops

Forces acting on an object that combine and form a net force that is NOT zero are:

• Balanced forces

• Unbalanced forces

• Gravitational forces

• Magnetic forces

The combination of all the forces acting on an object is called:

• Total force

• Net force

• Combined force

• Resultant force

An object at rest will stay at rest, and an object in motion will stay in motion unless an unbalanced force acts on the object. This is known as:

• Newton's 1st Law of Motion

• Newton's 2nd Law of Motion

• Newton's 3rd Law of Motion

• Law of Conservation of Energy

The tendency for objects in motion to resist changes to their direction and speed is called:

• Friction

• Inertia

• Momentum

• Gravity

A measure of the change in velocity during a period of time is called:

• Speed

• Acceleration

• Force

• Displacement

Like velocity, acceleration is a vector force. The length of the arrow indicates:

• the amount of speed

• the amount of magnitude

• the amount of acceleration

• the amount of mass

Acceleration is a change in velocity, which simply put is when an object:

• Changes direction

• Speeds up, slows down, changes direction

• speeds up

• slows down
