Newton's Three Laws of Motion

What force keeps the red block from sliding down?

• Gravity

• Friction

• Magnetism

• Tension

What is a push or pull called?

• A force.

• A motion.

• A reaction.

• An energy.

What is the effect of friction on motion?

• Friction has no effect on motion.

• Friction opposes motion and can slow down or stop moving objects.

• Friction increases the speed of moving objects.

• Friction only affects objects at rest.

What is the difference between speed and velocity?

• Velocity has direction, while speed does not.

• Speed is always greater than velocity.

• Velocity is a scalar quantity, while speed is a vector quantity.

• Speed can change direction, while velocity cannot.

What is velocity?

• An object's speed and direction.

• The distance traveled over time.

• The rate of change of position.

• The total distance covered in a journey.

What is the math formula to find force?

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

• Force = mass × acceleration (F = ma)

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

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

What does 'velocity' mean?

• Velocity means how fast something is moving in a certain direction.

• Velocity refers to the speed of an object without considering its direction.

• Velocity is the measure of how much time it takes for an object to travel a distance.

• Velocity is the total distance traveled by an object over time.

What is a 'net' force?

• The force that opposes motion.

• The total force acting on an object after all the forces are added together.

• The force exerted by gravity on an object.

• The force that is applied to an object to move it.

What unit is used to measure force?

• Pascal (Pa)

• Joule (J)

• Newton (N)

• Watt (W)

What is the difference between mass and weight?

• Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

• Mass and weight are the same; both refer to the amount of matter in an object.

• Weight is the amount of matter in an object, while mass is the force of gravity acting on that matter.

• Mass is a measure of an object's volume, while weight is a measure of its density.
