# Physics test questions Sketch a position-time graph for an object which is moving with a constant, positive velocity. To have "a constant speed in the negative direction" is to have a - velocity which is unchanging. To access released items from the computer-based tests: Physics is learned most effectively when your mind is actively engaged in the processes of analyzing and predicting.

An object whgich is moving in the - direction and speeding up slow to fast has a - acceleration. None of these objects change direction. If you both push in the same direction the door will swing round. An accelerating object has a changing velocity. At no point does his head explode. Temperature is a measure of how hot an object is A released-item answer key, provided for each ePAT, includes a crosswalk between the item numbering in the ePAT and the item numbers used in reports of student results for CBT test-takers. Even on Earth, gravity is not even. In the vacuum of space, your body fluids will vaporise, causing tissues to swell up. Objects A, B, D, and E.

At first, the line has a large slope corresponding to a large velocity and then the line has a small slope corresponding to a small velocity. Since the velocity is unchanging, the line is horizontal. Use the following graph to answer Questions 1 - 7.

At first, the line has a small slope corresponding to a small velocity and then the line has a large slope corresponding to a large velocity. Magnetism is a property of materials that makes them experience a force in a magnetic field. Since the slope of a line on a v-t graph is the object's acceleration, a horizontal line zero slope on a v-t graph is characteristic of a motion with zeo acceleration constant velocity.

It is the only object with an acceleration. Objects B and C. Object B has the smallest acceleration. Even the atoms in a solid vibrate around a fixed spot. Sketch a velocity-time graph for an object moving with a constant speed in the negative direction.

None of these objects change direction. Use the Show Answer! Thus, the line is a straight diagonal line with downward - slope. If the object is changing velocity from small to large values, then the slope must change from small slope to large slope.

Unlike poles attract because the magnetic forces are moving in the same direction. Which object s is are not moving? But what makes a metal magnetic? Use one of the following resources: Use one of the following resources: At first, the line has a large slope corresponding to a large velocity and then the line has a small slope corresponding to a small velocity.

Thus, the line is a straight diagonal line with downward - slope. Objects B and C. If the object is changing velocity from high to low values, then the slope must change from high slope to low slope.

The National grid provides electricity that reverses direction 50 times per second 50Hz in the UK. Electricity is the flow of any particle with a charge - in the case of our household supply, it is the flow of negatively charged particles called electrons hence electricity.

A position-time graph for an object moving in the - dir'n with constant speed; first a slow constant speed and then a fast constant speed is shown below.Your guide to physics on the web.
