A push, pull or twist on an object is, Buoyancy, Mass, Force, Friction, Forces can change the, movement of objects but only if they were already in motion, slow down or speed up objects only, speed, direction or shape of an object, Friction, What are the two types of forces?, Newton and Spring Balance, Unbalanced and Balanced forces, Motion and Friction, Contact and Non - Contact, Which of the following is NOT a contact force?, Two magnets brought together, hand on a bottle top to unscrew it, hand pulling shoelaces, schoolbag pulling down on shoulders, Which of the following is NOT a non - contact force?, Magnetic Forces, Gravity, Buoyancy, Electrostatic Forces, Forces are measured in units called, Joules, Metres, Kilograms, Newtons, Balanced forces act on objects that are:, Rising or falling, Stationary, Motion, All of the above, An example of unbalanced forces in action is:, a boat floating on still water, a person sitting on a chair, a rising balloon, A game of tug of war with equally matched opponents, Friction, occurs between any surfaces that are in contact and sliding past each other, pulls objects toward the center of the Earth., primarily affects objects that contain iron., None of the above, Rubbing your hands together creates, Mass, Volume, Gravity, Heat, Fluid friction is also known as, Slide, Drag, Grip, Move, Which of the following can friction can be a nuisance, Friction between a tyre and the road, Friction between feet and the ground from sliding, Rubbing hands together to keep warm., Sliding a heavy object across a rough surface, Which of the following can friction can be a nuisance, Friction between a tyre and the road, Rubbing hands together to keep warm., Friction between feet and the ground from sliding, Sliding a heavy object across a rough surface, Traction helps to keep strong contact on surface without slipping, True, False, Magnets can pull objects without actually touching them, True, False, The force between a magnet and an attracted object is an example of, Contact force, Magnetic Field, Friction, Non contact force, What do all magnets have?, North Pole, South Pole, Both, None, When the North and South poles of 2 magnets are brought together, the magnets, Attract, Attract, but force is weak, Repel, All of the above, Magnetic materials are:, Iron, Nickel, Cobalt, All of the above, The small groups of atoms that behave like small magnets inside a large magnet are called:, Domains, Poles, Iron filings, None of the above, Unlike poles:, Have no effect on each other, Repel, Attract, None of the above, Repulsion between a magnet and another object indicates that:, The other object is also a magnet, One has a north pole and the other has a south pole, The other is made of a metal that is non-magnetic, The lines of a magnetic field go from:, South pole to north pole, In any direction, North pole to South pole, It doesn't matter, The magnetic field of a magnet:, Only exists on the poles themselves, Is always as strong anywhere around a magnet, Weakens as the distance from the magnet increases, None of the above, In your own words, what is the definition of an electrostatic force?, Your own words, -, The components of an atom are:, Protons, neutrons, ions, Electrostatic, friction, contact charged object, Positive, negative, nucleus, Protons, neutrons, electrons, Provide an example of electrostatic forces?, Provide examples, Provide Examples, Each electron carries, Negative, Electrons, Positive, Nucleus, What are the 2 different types of particles in the nucleus, Protons and electrons, Protons and Nucleus, Protons and Neutrons, Electrons and Nucleus, Mass is usually measured in, Grams, Kilograms, KiloJoules, Milligrams, Weight is measured in, Newtons, Kilograms, Grams, None of the above, What is balanced forces?, Forces that are acting on the same object but are not the same size, Forces that are acting on the same object and are the same size, Equal forces, None of the above, What is unbalanced forces?, Forces that are acting on the same object and are the same sizeForces that are acting on the same object but are not the same size, Forces that are acting on the same object but are not the same size, Unequal forces, All of the above, The weight of a ship is balanced by, Surface tension, Gravity, Friction, buoyancy, Define buoyancy in your own words, Define Buoyancy, Provide examples
