Newton's Laws of Motion

What happens when balanced forces act on an object?

• The object will move to the left

• The object will move to the right

• The object will not move or accelerate

• The object will move and accelerate

What is the resultant force when unbalanced forces of 8N and 2N act on a race car?

• 6N deceleration

• 10N Lift

• 8N Acceleration

• 6 N Aceleration

According to Newton's first law, what will happen to an object at rest if no external resultant force acts on it?

• It will start moving.

• It will remain at rest.

• It will accelerate.

• It will change direction.

How can Newton's second law be used to calculate acceleration?

• By dividing force by mass

• By multiplying force and mass

• By adding force and mass

• By subtracting mass from force

According to Newton's third law, if a body A exerts a force on body B, what does body B do?

• Body B exerts an equal and opposite force back on body A

• Body B exerts an equal force

• Body B exerts an Increased force to unbalance Body A

• Body A exerts an Increased force to unbalance Body B

What is terminal speed in the context of a sky diver?

• The constant speed reached by a sky diver when the force of gravity is balanced by air resistance.

• The initial speed of a sky diver when they jump out of the plane.

• The maximum speed a sky diver can reach before opening the parachute.

• The speed at which a sky diver hits the ground.

What movement does the helicopter make?

• Helicopter moves froward and up

• Helicopter does not accelerate forward but goes up

• Helicopter hovers without moving in any direction

• Helicopter moves down and back

What is the effect of friction on a moving object?

• It changes the direction of the object.

• It increases the speed of the object.

• It decreases the speed of the object.

• It has no effect on the speed of the object.

What happens to an object in free fall when only gravity acts on it?

• It remains stationary.

• It accelerates downwards.

• It decelerates upwards.

• It moves at a constant speed.

How does mass affect the gravitational force between two objects?

• Gravitational force remains constant regardless of mass.

• Gravitational force is independent of mass.

• Gravitational force decreases with increased mass.

• Gravitational force increases with increased mass.
