Newtons 1st law of motion

How can you increase the speed of an object?

• By applying a greater force or reducing resistance.

• By decreasing the object's mass.

• By increasing the object's friction with the surface.

• By applying a constant force over time.

What is inertia?

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to accelerate.

• The speed of an object in a given direction.

• The mass of an object multiplied by its velocity.

What happens to a moving car if no forces act on it?

• It will come to a stop immediately.

• It will continue to move at a constant speed in a straight line.

• It will start moving in a circular path.

• It will accelerate indefinitely.

If an object is stationary (not moving) the forces acting upon it are _____________

• unbalanced

• balanced

• increasing

• decreasing

Give an example of Newton's 1st Law in everyday life.

• A book resting on a table will remain at rest until someone picks it up.

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

• A ball rolls down a hill due to gravity.

• A person pushes a shopping cart forward.

What does average speed represent?

• The total distance traveled divided by the total time taken.

• The total time taken divided by the total distance traveled.

• The maximum speed reached during a journey.

• The speed at which an object is moving at a specific moment.

What is the effect of balanced forces on an object?

• Balanced forces cause the object to accelerate.

• Balanced forces do not change the object's motion.

• Balanced forces make the object spin.

• Balanced forces increase the object's speed.

How does friction affect motion?

• Friction increases the speed of an object, making it move faster.

• Friction has no effect on the motion of an object.

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

• Friction only affects objects that are at rest.

What is the difference between speed and velocity?

• Speed is a vector quantity (magnitude and direction), while velocity is a scalar quantity (magnitude only).

• Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

• Speed and velocity are the same; both are scalar quantities.

• Speed is a measure of distance, while velocity is a measure of time.

What is the formula for calculating speed?

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Distance + Time

• Speed = Distance - Time
