1) How quickly something speeds up, slows down, or turns. a) Acceleration b) Law of Inertia c) Gravity d) Non-Contact Force 2) A force that happens when things touch. a) Work b) Law of Inertia c) Potential Energy d) Contact Force 3) The ability to make things happen or change. a) Inertia b) Contact Force c) Friction d) Energy 4) A push or pull that can make things move or stop. a) Speed b) Force c) Kinetic Energy d) Velocity 5) A force that slows things down when they rub against each other. a) Energy b) Velocity c) Contact Force d) Friction 6) The force that pulls things towards the Earth. a) Non-Contact Force b) Work c) Speed d) Gravity 7) The tendency of things to keep doing what they're doing. a) Work b) Friction c) Inertia d) Energy 8) The energy of movement. a) Work b) Kinetic Energy c) Power d) Energy 9) How much stuff something is made of. a) Friction b) Contact Force c) Kinetic Energy d) Mass 10) A force that acts on things without touching them. a) Friction b) Acceleration c) Non-Contact Force d) Kinetic Energy 11) Stored energy. a) Inertia b) Work c) Potential Energy d) Mass 12) How quickly work is done. a) Acceleration b) Power c) Friction d) Energy 13) How fast something moves. a) Power b) Friction c) Speed d) Work 14) Speed in a specific direction. a) Acceleration b) Kinetic Energy c) Inertia d) Velocity 15) The use of energy to move something. a) Action and Reaction b) Force c) Work d) Power 16) An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. a) Law of Inertia b) Friction c) Acceleration d) Action and Reaction 17) The acceleration of an object depends on the net force acting on it and its mass. It’s often written as F = ma, where F is the force, m is the mass, and a is the acceleration. a) Non-Contact Force b) Force c) Law of Acceleration d) Velocity 18) For every action, there is an equal and opposite reaction. This means if one object applies a force on a second object, the second object applies an equal and opposite force on the first object. a) Action and Reaction b) Law of Acceleration c) Speed d) Gravity
