Newtons Laws

What happens to an object at rest when balanced forces act on it?

• It remains at rest.

• It starts moving in the direction of the force.

• It accelerates in the opposite direction of the force.

• It changes shape.

What type of force(s) will cause a change in an object's motion?

• Balanced force

• Unbalanced force

• Frictional force

• Gravitational force

What is the effect of gravity on objects?

• Gravity pushes objects away from the Earth, making them weightless.

• Gravity pulls objects toward the center of the Earth, giving them weight.

• Gravity has no effect on objects, they float freely in space.

• Gravity only affects large objects like planets and stars.

How does friction affect motion?

• Friction increases the speed of an object.

• Friction has no effect on motion.

• Friction opposes the motion of an object, causing it to slow down or stop.

• Friction only affects objects at rest.

What is an example of an unbalanced force?

• A soccer ball being kicked, causing it to move in the direction of the kick.

• A book resting on a table, not moving at all.

• A car moving at a constant speed on a straight road.

• A person pushing against a wall without moving it.

What does Newton's 3rd law state?

• 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.

• Energy cannot be created or destroyed, only transformed.

What is the definition of 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 when a net force is applied.

• Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by a net external force.

• Inertia is the measure of an object's mass in relation to its speed.

What is the significance of Newton's first law?

• It establishes the concept of inertia and the idea that an object will not change its state of motion unless acted upon by a net force.

• It states that for every action, there is an equal and opposite reaction.

• It describes the relationship between force, mass, and acceleration.

• It explains the behavior of objects in circular motion.

What is the tendency of objects to resist a change in motion called?

• Inertia

• Momentum

• Friction

• Acceleration

How can you describe the motion of an object with no net force acting on it?

• The object will accelerate in the direction of the net force.

• The object will remain at rest or continue to move at a constant velocity.

• The object will eventually come to a stop due to friction.

• The object will change direction randomly.
