Newtons Law of Motion

What is the role of gravity in motion?

• Gravity is a force that repels objects away from each other.

• Gravity is a force that attracts objects toward each other, affecting their motion.

• Gravity has no effect on the motion of objects.

• Gravity only affects objects that are in space.

What is Newton's Third Law of Motion?

• For every action, there is an equal and opposite reaction.

• An object in motion stays in motion unless acted upon by an external force.

• The force of gravity is proportional to the mass of the objects involved.

• The acceleration of an object is directly proportional to the net force acting on it.

What happens to a moving object when no net force acts on it?

• It comes to a stop immediately.

• It continues to move at a constant velocity.

• It accelerates in the direction of motion.

• It changes direction randomly.

What is the formula for calculating force?

• Force (F) = mass (m) × acceleration (a)

• Force (F) = mass (m) + acceleration (a)

• Force (F) = mass (m) / acceleration (a)

• Force (F) = mass (m) - acceleration (a)

What is Newton's First Law of Motion?

• An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• An object will accelerate in the direction of the net force acting on it.

• For every action, there is an equal and opposite reaction.

• An object in motion will eventually come to a stop unless acted upon by a force.

What is the effect of friction on motion?

• Friction can increase the speed of an object.

• Friction can have no effect on motion.

• Friction can slow down or stop the motion of an object.

• Friction only affects objects in motion.

What is the significance of the net force?

• It is the total force acting on an object, determining its acceleration.

• It is the force that opposes motion.

• It is the force that acts only when an object is at rest.

• It is the force that is always equal to the weight of the object.

What is an example of Newton's Third Law in everyday life?

• When you jump off a small boat, you push the boat backward as you move forward.

• A ball thrown in the air comes back down due to gravity.

• A car accelerates when the driver presses the gas pedal.

• A person pushes against a wall and the wall pushes back.

What is friction?

• A force that accelerates an object.

• A force that opposes the motion of an object.

• A force that increases the speed of an object.

• A force that changes the direction of an object.

What is inertia?

• Inertia is the tendency of an object to resist changes in its state of motion.

• Inertia is the force that causes an object to accelerate.

• Inertia is the speed of an object in motion.

• Inertia is the mass of an object multiplied by its velocity.
